Plugin localization

Dear friends,
I like your great plugin Page Builder very much. I have just a problem with its localization into my language. There are some strings, which were translated by me in the language file, but they are still displayed English originals and not my translations.

See https://www.evernote.com/shard/s6/sh/6d1f150a-607a-4f9d-8430-9e3cb5c0ddff/6205a5c30ad480a2ead7bcb81bc44cf7 .

Can you pls have a look at it?

Thanks a lot,

Martin
