Lostful

this is the exact way I've seen it done in every video covering this, but instead of there being a .sav option like there was for everyone else, this is all I get. no matter how I save it, it is not able to be re exported into my game.

I am new to Pokémon emulation and pkhex, however I have had no issues up until this point of using pkhex. I am currently playing on emerald, emulating through VirtualBoy emulator, I exported my save file it to pkhex and edited my save file with everything I needed. the issue is when I try to export the file from pkhex, it only saves the file under "all files" or under "SAV3E" file, neither of which allow me to import the file back into the emulator, as it needs to be a .sav file, I just don't have that option. I have done everything, ensured it is under Pokémon emerald, and tried installing several times using multiple methods. this is very frustrating, and I have not gotten any clear answers on how to fix this.
