Filemanager shows owner id (number) but not the name

[flexjoly]

Hi,

I am playing around to get the ownership right for git-deployment by hooks.

For some files now DA only shows the nummeric ID as user or group. But when i lookup the dir with 'ls -al' the names are shown normally in the ssh shell.

Have i done something wrong? How can i fix this?
I tried to google it, but could not find it yet.

Thanks in advance,
Greetz, flexjoly
