Solved Proftpd doesn't recognize Group-Membership

Hi Folks,

i'll bite after searching for hours:
FreeBSD 12.1-p2 with ProFTPd 1.3.6b
ProFTPd doesn't recognize Group-Membership of the logged in user

The designated Folder has ownership "root:TheGroup" with 0775 Permissions, and i'm a member of that group (it's not a system-group, the GID>1000)
I can log in, read files (download), everything fine.
The other way round (Upload) fails. FileZilla says: 550 Permission denied.
Huh?
The same Folder (exported via Samba) works fine from any Samba-Client (read and write incl. Group-Ownership-change).
If i change ownership to "zvoni:TheGroup" it works (as expected).

What am i missing?

I first thought it was because ProFTPd was running inside a Jail, but it's the same when running outside the Jail.
/usr/local/etc/proftpd.conf is pretty much a stock-file just added TLS-stuff and a <Directory>-Directive

That's the output of ProFTPd -V
