There must be something wrong with the file. As you can see the Duration of the file is not ok as well. Have you loaded one of these in a Wave / Audio Editor to see if they have some garbage in? Where do you got the files from?Did they had this size already before loading them into Engine Prime?
Put them through mp3 scan + repair. Something isn’t right with the mp3
some several days have gone since this was asked first.
Was a reasoning found of this?
