Adobe Animate Video Export Symbol Loop Issue

Just made an animation where my character's brows move up and down and his eyes look to the right once in a while. I did this by making the character a symbol and then executing these steps inside the symbol as one would. The loop was really neat but when I export it to mp4 video the brows move more frequently and not like the way I spaced the keyframes around when making it. Anyone had this issue in the past?

Thanks!
