Can't get sprinting sprite to play loop (Paper2D)

I’ve been working on a 2D platformer in Paper2D (I’m VERY new to Game Dev). I’ve gotten basic movement controls down using Enhanced Input Actions and I’ve been trying to implement a sprint function. I’ve gotten the sprint to work, however when I try to set my sprites flipbook to my sprint animation it will not loop through when activating sprint. I have tried setting looping and not setting looping in the blueprint, neither will work. The character just gets stuck on the first frame of the sprinting animation.
