Corrupted samples

Hi everyone, I'm making some jinriki banks and have been having some trouble with samples just not playing even though they play when tapped on and I can see it in the oto sector (sorry I'm not sure what it's called specifically) so I know the sample is there, and the others are playing fine, certain ones are just making a little bump sound instead. I was wondering if there's any way I could force them to make a sound with having to edit a whole new replacement?
