After Converting my Unreal Project from 5.2 to 5.3 the level sequences are behaving differently

So I converted my project from 5.2 to 5.3, and the level sequence is acting weirdly. On 5.2 everything was fine. I tried to reimport animations and make new level sequences but still no luck. Is there anything new on 5.3 that I am missing? Help is much Appreciated.
