Group member disappear


I created a group called “intern” with ~10 Members and then I created a category called “intern discussions” that can only be accessed by this group of interns.
Works fine … except that some of these members randomly just disappear out of the group. One of them I added 4 times already and tends to disappear again after an unkown period.
Any hints or ideas what could be the reason?
Is Inactivity an issue?
‘Allow users to leave the group’ is disabled

thank you
