translation problem

I'm not sure, but after installing vData on a second website (Joomla 3.6.4) it looks like if certain fields aren't translated right. See printscreens:

It seems you have created language files for any other language. There is some issue with the language files you created, Please check it carefully, It hopefully will resolve the issue.
If this is not the case, Please uninstall and install the extension again.

the thing is, its a clean installation of Joomla and I didn't do anything with language files. I also un-installed vData and installed it again, but same result
