Weird preview thumbnail playback speed problem

While previewing my animations, I noticed that one of my animations is playing at a different speed and not the default 1x speed. I tested previewing my animations on various mobile browsers on my android phone and iPad, the results are the same so I thought I would screen record from my iPad. The singular animation plays at a faster speed on Chrome and Safari but on Firefox it plays at a slower speed. I checked through more pages of my previews and it seems like that is the only animation displaying like this. Please check the linked screen recordings for reference
