Accent Hits Cut Off

Hey everyone, I’ve got a question for anyone who might have used extended length .wav samples for the accent hits. I’ve created two other songs with whistling parts placed in the Accent Hit and didn’t seem to have a problem getting them to play fully. However, I’m now trying to do a third one and for some reason the accent keeps getting cut off. I thought at first it might have been due to the length of the midi loop or fill that it was being played in was possibly too short… but I extended it and it still gets cut off. Same goes if I press the accent during the intro or the outro even though both are longer than the accent itself. I also thought maybe there was a limit to only 3 bars for an accent hit… but in one of my other songs, I have an 8 bar accent during a Fill.
Any ideas here? Any reason why accents would get cut off?
