It can be reproduced in dmaster following the next steps:
- Go into dmaster
- Create a Smart Group
- Add "Manually" a Contact in the Smart Group
- Go to the Contact (the counter in the Group Tab shows a number, p.ex. 0)
- Access to the Group Tab
- Now the counter has been updated into 1 because the contact is in a Group
It's a normal behaviour? Or can it be considered as a bug?
