I don't see a mistake there. If your file is named "myawp.mdl", of course you will write "my_awp.mdl" and not "v_myawp.mdl" in the file. Use your brain, please.
There is no part in the code that checks if the filename contains "v_" or something like that and there's no reason for it to have such a thing.
