Azure AD Gui is not showing all synchronized groups

[TheM365Guy]

Hey guys, I have a curious phenomenon. We have a federated sync with our AD and the AAD. We created a few universal groups for managing some features. Now I checked the AAD and the group is not showing up. But just a few of them. So I reviewed the sync - everything looks good. I checked then with powershell module - group is there! But I can not see it in the GUI management. 

Any ideas? Is this is a bug or something? Actually I don't find any articles about that behavior.
