Can't delete or add groups

(4.3.1)

I tried adding a group and deleting one (no members left in it). After I delete it (and it disappears from the groups list) if I go back to the page it shows again.

I also created 2 new groups. They do not show in the groups list, but if I assigned a user to the group when I created it the user shows they are assigned to the invisible group.

Can’t reproduce with 4.3.2. Do you see anything relevant in the logs? What database you use?

We use the built in HSQL DB.

They showed up. It apparently just took some time (5+ min) to reflect in the console page.
