Folders in external storages via SMB/CIFS have " Dr" at the end

Hello to Nextcloud community,
my new Nextcloud on new Debian with smbclient (2:4.13.13+dfsg-1~deb11u2) has a problem with names of directories – their names are ending " Dr", for example "Multimedia Dr" (without quotes, 25 spaces), so they are inaccessible by clicking… :frowning:

Does anybody know the solution?

Thanks a lot for any suggestion…

Nextcloud version: 22.2.0
Operating system and version: Debian 5.10.70-1
Apache or nginx version: 2.4.51-1~deb11u1
PHP version: 2:8.0+85+0~20211110.38+debian11~1.gbp73ad3b
Is this the first time you’ve seen this error? Yes, new installation. (Tried two times, on two separate virtual machines.)

Is there a dot at the end of the directory name? This does not work with Windows as far as I know.

Well, if I use CLI (bash) via smbclient, i see dir:
Multimedia Dr 0 Sun Nov 21 16:11:43 2021

If I mount it via /etc/fstab, i see normal dir “Multimedia” (without any dot at the end).

Old ownCloud 9.1 on another machine works well with same share and same directories…

Anybody any tip?
Can’t use SMB/CIFS, so my Nextcloud is useless… :frowning:
