Epxse(Android) does not detect my progress downloaded from the cloud ¡¡HEEEEEEEELP!!

[Zaturno Dominicano]

Previously I was playing Castlevania:Symphony of the Night for several months until I reached the end of the INVERTED CASTLE just before the final battle against Dracula. after that I decided to upload the save SLOTS from the root folder of the emulator to Google Drive. And from there I have lasted many months without playing it, but when I go back to continue my game where I left off the last time I played it, it directs me to Google Drive to download my Castlevania save SLOTS and then take it to the root folder of the emulator (after reinstalling the latter) and when I start the game and go to the Saves state menu, none of the slots that I had downloaded from the cloud appears. It was even the same version of the region of the game with which I saved these slots (the one from the game downloaded from the cloud) but anyway it does not detect it. Please help me, it took me a long time to get to where I am in the game and I'm too lazy to repeat everything from zero.

By the way, the version I played is PAL, the European version of the game (SLES 005.24).
