Spring Cloud Data Flow Grafana Prometheus not showing stream data - spring-cloud

Question

I launch Spring cloud data flow with docker-compose base on this website.
https://dataflow.spring.io/docs/installation/local/docker/
I created 3 apps, Source, Processor & Sink.
I ran
export STREAM_APPS_URI=https://dataflow.spring.io/Einstein-BUILD-SNAPSHOT-stream-applications-kafka-maven
When I run docker-compose -f ./docker-compose.yml -f ./docker-compose-prometheus.yml up, all my containers start up as specified in the docker-compose.yml and docker-compose-prometheus.yml.
I proceed to register the 3 applications and then create a stream with them.I then run it.
Question 1:
The status of the stream is always "Deploying". Shouldn't it be Deployed?
Question 2:
When I click on the "Grafana" icon, it launches the Grafana page but there is no data on it. Why is it so? I am using kafka as my messaging middleware as shown below.
