Smart Filter Bar does not appear - sapui5

Question

I am trying to use SmartFilterBar as follows:
<VBox fitContainer="true">
<smartFilterBar:SmartFilterBar id="JobProfileOverviewFilter" entitySet="ProfileSet">
<smartFilterBar:controlConfiguration>
<smartFilterBar:ControlConfiguration key="Item"></smartFilterBar:ControlConfiguration>
</smartFilterBar:controlConfiguration>
<smartFilterBar:layoutData>
<FlexItemData shrinkFactor="0"/>
</smartFilterBar:layoutData>
</smartFilterBar:SmartFilterBar>
<smartTable:SmartTable id="JobProfileOverview" entitySet="ProfileSet" tableType="ResponsiveTable" useTablePersonalisation="true"
showRowCount="true" enableAutoBinding="true" smartFilterId="JobProfileOverviewFilter" header="Business profiles"
class="sapUiResponsiveContentPadding" app:useSmartToggle="true">
<smartTable:customToolbar>
<OverflowToolbar design="Transparent">
<ToolbarSpacer/>
<OverflowToolbarButton icon="sap-icon://order-status" tooltip="Order status" text="Order status" press="onStatus"/>
</OverflowToolbar>
</smartTable:customToolbar>
<!-- layout data used to make the table growing but the filter bar fixed -->
<smartTable:layoutData>
<FlexItemData growFactor="1" baseSize="0%"/>
</smartTable:layoutData>
<Table mode="MultiSelect"></Table>
</smartTable:SmartTable>
</VBox>
The problem is, the filter does not appear on the screen.
the cutout from the metadata:
<EntityType Name="Profile" sap:content-version="1">
<Key>
<PropertyRef Name="ItemId"/>
</Key>
<Property Name="Item" Type="Edm.String" Nullable="false" MaxLength="300" sap:unicode="false" sap:label="Role" sap:creatable="false"
sap:updatable="false" sap:sortable="false" sap:filterable="false"/>
<Property Name="Connector" Type="Edm.String" Nullable="false" MaxLength="32" sap:unicode="false" sap:label="System" sap:creatable="false"
sap:updatable="false" sap:sortable="false" sap:filterable="false"/>
<Property Name="Descn" Type="Edm.String" Nullable="false" sap:unicode="false" sap:label="Description" sap:creatable="false"
sap:updatable="false" sap:sortable="false" sap:filterable="false"/>
<Property Name="ValidFrom" Type="Edm.DateTime" Nullable="false" Precision="7" sap:unicode="false" sap:label="Valid From"
sap:creatable="false" sap:updatable="false" sap:sortable="false" sap:filterable="false"/>
<Property Name="ValidTo" Type="Edm.DateTime" Nullable="false" Precision="7" sap:unicode="false" sap:label="Valid To" sap:creatable="false"

sap:creatable="false" sap:updatable="false" sap:sortable="false" sap:filterable="false"/>
<Property Name="Selected" Type="Edm.String" Nullable="false" MaxLength="1" sap:unicode="false" sap:label="Boolean" sap:creatable="false"
sap:updatable="false" sap:sortable="false" sap:filterable="false"/>
<Property Name="ItemId" Type="Edm.String" Nullable="false" MaxLength="50" sap:unicode="false" sap:label="Object ID" sap:creatable="false"
sap:updatable="false" sap:sortable="false" sap:filterable="false"/>
<Property Name="ItemType" Type="Edm.String" Nullable="false" MaxLength="6" sap:unicode="false" sap:label="Item Type" sap:creatable="false"
sap:updatable="false" sap:sortable="false" sap:filterable="false"/>
</EntityType>
<EntitySet Name="ProfileSet" EntityType="YGAC_ACCESS_MANAGER_SRV.Profile" sap:creatable="false" sap:updatable="false" sap:deletable="false"
sap:pageable="false" sap:content-version="1"/></EntityContainer>
What am I doing wrong?
Update
I have enabled the filter now
But it does not appear in SmartFilter:
I have to enable it in the filter option:
Why the filter fields do not get shown as default?

Try to add other parameters, for example:
<smartFilterBar:ControlConfiguration
key="Item"
mandatory="auto"
preventInitialDataFetchInValueHelpDialog="false"
visibleInAdvancedArea="true"
controlType="auto"
displayBehaviour="idAndDescription"
label="Item"
index="1"></smartFilterBar:ControlConfiguration>
