fluidcontent_core: hide headline in customized content elements - typo3

Question

I am pretty new to Typo3, Fluid etc. and I can't solve the following problem:
I don't want fluidcontent_core to render the headline of my customized content element. Therefore I created a new template with an appropriate layout but the headline gets still rendered.
I've been looking for a while now and can't find my mistake. It would be really nice if someone can help me!
I've already added the layoutRootPath and the templateRootPath to the fluidcontetn_core plugin.
In the template where the CE is added I render the content with <v:content.render column="1" />
template of the customized content element:
<div xmlns="http://www.w3.org/1999/xhtml" lang="en"
xmlns:f="http://typo3.org/ns/TYPO3/Fluid/ViewHelpers"
xmlns:flux="http://typo3.org/ns/FluidTYPO3/Flux/ViewHelpers"
xmlns:v="http://typo3.org/ns/FluidTYPO3/Vhs/ViewHelpers">
<f:layout name="Content" />
<f:section name="Configuration">
<flux:form options="{group: 'Carousel'}" id="carousel" label="Carousel">
<flux:grid>
<flux:grid.row>
<flux:grid.column name="Content" label="Carousel Content" />
</flux:grid.row>
</flux:grid>
</flux:form>
</f:section>
<f:section name="Preview">
<flux:widget.grid />
</f:section>
<f:section name="Main">
<section class="kundenlist carousel slide frame" id="kundenlist" data-ride="carousel">
<div class="carousel-inner">
<flux:content.render area="content" />
</div>
<ol class="carousel-indicators visible-xs">
<li data-target="#kundenlist" data-slide-to="0" class="active"></li>
<li data-target="#kundenlist" data-slide-to="1"></li>
</ol>
<ul class="carousel-navigation hidden-xs">
<li>
<a class="left" href="#kundenlist" data-slide="prev">
<span class="icon-carousel-prev"></span>
</a>
</li>
<li><span class="js-active-slide">1</span> / 2<!--bei dynamischer Generierung fix reinschreiben--></li>
<li>
<a class="right" href="#kundenlist" data-slide="next">
<span class="icon-carousel-next"></span>
</a>
</li>
</ul>
</section>
</f:section>
layout of the customized content element:
{namespace flux=FluidTYPO3\Flux\ViewHelpers}
{namespace v=FluidTYPO3\Vhs\ViewHelpers}
<f:layout name="Content" />
<f:if condition="{settings.content.settings.container.addAnchor}">
<a name="c{record.uid}"></a>
</f:if>
<v:tag name="{v:variable.get(name: 'settings.container.types. {record.CType}') -> v:or(alternative: settings.container.types.default)}"
class="{settings.content.settings.container.className}">
<f:render section="Main" />
</v:tag>
