Hi,

In our production and integration systems some groups got duplicated. Meaning that in CMS -> Admin -> Content Type -> (any content type) -> Property Editing -> opening Tab dropdown -> some groups appear several times in the list.

It is only happening on two systems, although the same code is on several other systems actively used by developers. The integration system is mainly used by the client, who is heavily using CMS layout reconfiguration features.

I could not reproduce the issue locally. The CMS table tblPropertyDefinitionGroup has the following contents (anonymized):

As you can see, several entries appear multiple times in the table as well. Using CMS 11.13. Running in load balanced environment. Is this a known bug? I tried deleting the table locally, it gets recreated, although some groups not defined by us will not be recreated. GroupOrder will be also -1, although it is defined in code (although in the original table it seems to be also missing at most entries). Is this a safe workaround for the issue? Thanks
