Many sites (with ssl and without) on 1 ip in ispmanager 5 how bad is it?

A VPS with ISPmanager 5 lite
ip address 1 PC.
In the panel about 40 sites (some with ssl certificates)
Faced with the fact that in some services with verification of the correct installation of an ssl certificate ( https://www.wormly.com/test_ssl or https://www.ssllabs.com/ssltest/index.html ) when checking the graph Valid for the Host Names and the like is another of my website. While everything works like normal (the sites are loaded without problems).
Also found ( through the service https://www.mail-tester.com ) that when sending EMail from the site in the service header is (already 3rd) site (also mine).
The feeling that configured 1 config that applies to all domains and some of them are dominant, which for some reason, always POPs up.
How critical is it in General and PS in particular? Can it be resolved?

Solved. Please contact the staff. No diagnosis nothing will not say.
p.s. Adjust hostname, PTR and priority domain. To begin with.
