Problem with tags, I am translating correctly osp

I'm changing the labels of language in the translation list and then, for no reason change like the image attached, and once carge the language file of frontend and backend, and I'll have to do it again because failure.

When you have made the correct translation I can give them the language file.

It seems you are losing the language content too much. If you are using English,
you can copy the corresponding files from
language > en-GB > en-GB.com_osproperty.ini and change the text from that file directly.
The same for other languages.
Thanks
