Hi Anna,
Thanks for your help with this. Next time if a plugin doesn’t have a .po file for your language, you can use the .pot file and resave it. The test file was a little outdated so there are some strings you didn’t get to translate. I have updated the file you made with the new strings. Please download it from here and complete it. Don’t worry about the .mo file- I can generate it myself, as long as you send the .po file. Once you do that, I’ll test it out and then send you a coupon for a free license for Filter Bar.
Best,
Leah
