Animation Speeds Up

I have Toon Boom Studio 8, and everytime I make an animation, it goes faster than the way I animated it in the program.
Everytime I have to change the speed of the exported video in a video editor (I usually have to change it to x0.5 speed) because it’s at a different speed than what I animated IN the program.
The sound also doesn’t match up to its visual on the timeline, and the sound ends early in the time line before reaching the end of the sound file’s visual bar end.

it’s a very strange issue, and I’m hoping someone knows how to solve it?
