Translation changing by itself

This is not an issue with the file editor. My plugin doesn’t modify anything without your explicit action.

I can’t tell you for sure, but see this FAQ:
Why have my translations been reverted?

the problem is that the loco t comes out to me that, indeed, they are translated but in the visualization no

Is it correct to translate this way? -> https://docs.listingprowp.com/knowledgebase/how-to-translate-listingpro/

That page shows the saving of translations files in the “Author” location, which means inside the actual theme/plugin folder. This is NOT recommended.

From the FAQ link I posted above:

When WordPress updates a theme, any translation files under the theme’s folder will be replaced. NEVER save your own custom files in this location!

This is all very well documented. Please read Choosing a location to save your files.

I have same problem. I’am changing woocommerce translation file for a feh string. There was any problem for 1 year. But after latest update, loco translate rolling back to woocommerce translate file. I change it again, a few day later it rolls back again…
