APM services not listed in Kibana APM

Using v 7.5.1 of Kibana, Elasticsearch & APM-server.
I am able to see the data in discover tab, but not in the APM tab.
I have gone through the recommendations in the guide & other forums,
index name is kept standard apm-*, templates not changed.
Index patterns & Index template visible in the Kibana management tab.

IN the APM setup it shows -
under server - APM Server has still not connected to Elasticsearch
under agents -
Data successfully received from one or more agents
1 of 1 objects already exist. Click 'Confirm overwrite' to import and overwrite existing objects. Any changes to the objects will be lost.

I have java agents & rum agent data

Hi Team, any help on this ?
