the EA launcher has deleted my game files and asks me to download everything aga

First use (maybe second because I played briefly a game with the EA app a long time ago,
maybe only 2 hours) of the EA launcher, and well I have to say I'm disgusted!

I downloaded a game yesterday and the download ended while I was sleeping, my connection is bad so it's really taking me a while. I wake up with the hope to play a little, and there problem with my connection of a few minutes: not big problem, I close the app and reopen the EA app again: the game download goes back to 0,
but the game files in the directory folder are there, so the game is downloaded but the EA app asks me to download everything again.

I see the info that you have to try to change the directory of the game folders and empty the cache, so I do that, and change the directory, close and open the EA app again and then I click on download (hoping that the download "resumes" and the app tells me that I can finally play). and then the app deletes all the game files in the directory and tells me that I have to download everything again, of course! if you deleted everything, you have to start from 0... well, great experience! I'll remember it, I don't even know if I want to play right now. Can I be helped? I don't have much hope of finding these files I guess I have to download everything again...
