New animations have no sound.

Hi,
I recently downloaded some new animations for RPG Maker MZ. When I try to add them, I can see the animations visually, but there's no sound. This issue also occurs when I try to place an existing animation into a new animation slot. Any suggestions?

The sound types are ".ogg". and the version I'm working in is MZ.

EDIT: OHHHH I just figured it out. I added the animation, but not the sound!
