Universal security group in active directory keeps changing

We have had a universal security group setup that is used for email distribution and permissions.
Over the past three weeks we have noticed that somehow all of the members are getting removed and the group becomes a member of itself.
We haven't been able to figure out why it's happening, but it appears to be happening in the overnight hours because I check it throughout the day and the membership is okay. When I check in first thing the next morning the changes have been made.
I have tried installing the free version of Netwrix Active Directory change reporter, but it isn't showing anything about the changes happening to that group or members of the group.

Have a look if you have a group policy that is applying a Restricted Groups setting. On the policy under Computer Configuration click Policies, then Windows Settings, then Security Settings. Go to Restricted Groups. Look if anything is specified there, if so the setup is most likely wrong.

The group name should be the actual domain group name so domain.com\group name. Next in the property of group you will see two textboxes. One is called Members of this group. Any user or group added in this box will be the default for the domain group. So even if you correct the domain group in AD and add new users when the policy fires it will remove these users and only leave the ones specified in the restricted group policy.

This is the most likely place where your issue is coming from.

The explanation was very quick and clear.
I was able to find a group policy that had restricted groups and have since removed the settings.
