translations not visible

I am using V1 and did everything right. The odd thing is that every string is translated except for strings that contains ‘Places’. Is there some kind of default setting that prevents this?

I used method num,ber 2 and with no result. I will try method nr 1

I am trying to change the name for Places in the admin and several other places on the website

Strange thing is that in my development environmet I succeeded to do that through the language file but not in my production site.

What I can see is that the CPT names are different. In the first it is ‘Places’ and that I can translate without problem, in the second it is ‘Hele overzicht’ (based on the dutch translation that I made) Somehow that translation got ‘stuck’ and cannot be translated again through the language files. Is the CPT name somnehow stored in the database?
