Dreamweaver CC 21.6: Bug - File lists only showing name

Windows 11

In both - local and remote - file lists it's noch possible to switch on futher colums (like size).
The headline appears shortly, but disapperars immediately without any visible result.

I already tried to move the column-divider (what has helped in former times) - not working.

I need urgently to see rechent changes dates.

Please help!
