Some audio clips getting cut at the end for no reason

I can usually import sound clips without issue, though sometimes the ends of the clips are cut short for no reason. The whole clip is shown to be there as one long key in the sound layer, but the actual sound stops before the play thing reaches the end of the key. Usually I can just fiddle with it and it magically sorts itself out, but right now I’m having difficulty. It just won’t fix. It has no reason to do this. I have literally a bunch of other audio clips that are just fucking fine, but now all of a sudden any and all sound clips I import get cut short for no reason. There is no difference between a clip that works and a clip that doesn’t work. It’s a Pencil2D problem that has no reason to exist. Sorry, I said “no reason” like infinity billion times. Illogicalness pisses me off.
