Strange writings in the translation head

Hi all,
Can anyone tell me why some fields in the translation have been changed? I can’t figure out what function has filled the fields.
For example, as you can see in the SCREENSHOT, the translation of “Claim” is:

-#-#-#-# _directories-pro-it_IT.po (unnamed project) #-#-#-#-

Gestisci -#-#-#-# directories-payments-it_IT.po (unnamed project) #-#-#-#-

Richiesta Gestione

I never wrote all this, but I only wrote “Manage”
What’s going on?

Regards
Umberto
