Looking into it: Yes, you are perfectly right. Problem solved. Thank you.
As a matter of fact I knew textstrings come from different sources. Just didnt look deeply enough. (=Didnt control enough plugin languagefiles).
Actually it is quite bothersome the localization are split up in so many files. It might be easy for the programmer, but not very friendly for me as a user and a validator.
1. I have to download and upload at least 3 files and maybe 10-20 more depending on how many plugins i use to get a full localization
2. I have to look about 25 places to check if anybody has added translations that need validation. I found translations more than one year old not validated. I tend to validate what is usefull for me, but likes to validate other stuff as well. But if it is bothersome to do, well, it will be done seldom or not at all.
3. Having 3 versions of Simple press and 4 themes doesnt improve things. As far as I have checked the files for admin, the files for frontend and the files for themes doesnt differ very much. So you might consider making a single catch all file(well an adminfile, a frontendfile and a themefile in the present setup).
Actually a single file for ALL would be preferable for the user (and validator).
That was my point of view
. You probably have other issues.
