language-switch didn't recognised

[maflemming]

Hi !
I've use darktable 3.8.1 and Ubuntu 20.04

flemming@bigone:$ darktable --version
this is darktable 3.8.1
..and configured the language for the plugin in german

flemming@bigone:~/.config/darktable/lua/locale/de_DE/LC_MESSAGES$ ll photils.po
-rw-rw-r-- 1 flemming flemming 1945 Feb 1 23:34 photils.po

using the script-manager

flemming@bigone:~/.config/darktable$ cat luarc
require "tools/script_manager"
require "contrib/photils"

but the language of pluggin ist still always in english ... what's going wrong ?

or should i switch to the darktable-lua-github-queue ?

thanks & cheers

flemming
