For some reason media encoder changes the position and repeats a section of my composition when exporting.

Media encoder output

This issue occured when I tired to render the composition in Quicktime Format. It affects the output of the video, and when I try to switch back to H.264, the updated position+repeated edge persist.
I managed to replicate this exact issue with a totally different composition using the same steps which makes me think its a media encoder issue.
