downloaded resource packs don't apear

I downloaded a couple resourse packs off of the internet then using file explorer, I put the files in the resource pack folder. but when I opened minecraft, none of the resource packs have loaded in. I'm sure that they work because I tested them on my phone and they loaded just fine.

the only packs I see are the ones which I have previously downloaded, and upon deleting them from the files, they don't disappear from in game.
