Error message while submitting to repository

[Fòram na Gàidhlig <fios foramnagaidhlig net>]

While trying to submit this translation to the repository:

https://l10n.gnome.org/vertimus/gtk+/master/po-properties/gd

I got the following error message:

An error occurred during applying your action: The commit failed. The 
error was: '[Errno 1] remote: translations user cannot modify 
'po-properties/gd.po' To ssh://git.gnome.org/git/gtk+ ! [remote 
rejected] master -> master (pre-receive hook declined) error: failed to 
push some refs to 'ssh://git.gnome.org/git/gtk+' '

I have submitted other stuff, so I guess it has to do with project 
permissions?

Which module do I report the bug on?
