Title, Description, "Accept terms" not translatable

Hi!
I am trying to translate %s Title and %s Description for the Add Listing site, but I cannot even find them in any of my *.po files.

Those values are not existing in my files…
Furthermore I am trying to translate the “accept terms and condition” link. I could find this one in my geodirectory-de_DE.po file and I was assigning a translation to it, but it did not show up afterwards.

Furthermore I have an issue with the file upload translation:I was translating the corresponding “select files” text, but it only shows up everywhere.
When I added a custom fields upload button, still the english version “select files” is displayed. I also dont find any reference where I can translate it.

Thx
