Columns in Views are not saved

We’re facing a problem in Views. Columns are not saved. All views are showing the standard columns.

Both M-Files server and Desktop are running on latest release (23.4.12528.8).

The same problem was also encountered with a previous server release (22.5.x). We expected to solve it with an upgrade to the latest release.

To solve the issue we have already performed a:

 

Clear local cache.

Restore default settings (User-specific settings)

Destroy local data (Computer-specific settings)

Remove / Add Document Vault Connections

 

Anyone with other suggestions to solve this?

Thanks!
