Ducth files .mo and .po polylang

Hello,
I don’t find the .mo and .po ducth files in the new version of Polylang and my theme is in 3 different languages and one of them is Dutch (Netherlands). Although I modified code to change some strings that I couldn’t see in Polyland due the my theme, everything works fine in Spanish and English but this strings was missed since I uptodated to the last Polylang version. My website where you can check my problem is: https://www.longletsbenidorm.es. I hope somebody can help me a.s.a.p. Kind regards.
