RNA Label Error "Matches several messages in po file"

Hi, can someone tell me what this means and how to fix it?
I’m translating Blender’s UI into Swedish, it’s working but the .po file seems to not have the errors that the RNA label complains about. Every single button in blender shows this RNA error when I right click & “Edit Translation”.
Again, I’m studying the .po file both with poEdit and Notepad++ but no apparent errors or double labels…

Any ideas?
Best Regards
