Reset language files

Hi, please can you help me? I made new translations for "The Events Calendar" and the "Event Tickets" Plugin. The files are saved here: languages/loco/plugins/event-tickets-de_DE.po
(so i think this is a save place - right?)

And every day automatically there where a new system language created, and override my modification:

I don't know where there could be a mistake. I use the Avada theme, with "Event Tickets", "Event Tickets Plus", "The Events Calendar" and the "The Events Calendar Pro" Plugins:

 Thanks for your help.

Nice regards
