Licensed Sessions display 0 sessions

Hi All,

I have never faced this before, but I have a DB with license type Application Builder, where my issue is that Licensed Sessions=0.

There should be at least 52 licensed sessions, since license has 52 concurrent users.

I am the super user, have DBO permissions on database, and have access to open page Session List.

Do you have any idea why I cannot see all sessions on database from DEV environment?
