Lottie scroll animation lag on first playthrough, fine on subsequent ones

Hello, I just started using Webflow and this is my first project. I have a lottie animation with a scroll interaction (the ufo) that looks to be working as intended, but I noticed the first time it runs through it’s animation, it lags/jumps a bit at certain points. I’ve switched it between SVG and Canvas as I saw in a similar thread but neither option seems to have a noticeable affect. As far as I can tell, the animation only shows this lag on the first runthrough and any subsequent run throughs are smooth as butter.

Any help or insight with this issue would be greatly appreciated, thanks!
