After Effects Sequence Not Filling Screen In Premiere Timeline

I'm trying to import an After Effects sequence into Premiere using the method of opening the AE project from Premiere and then selecting the timeline I want to import. Once imported and added to the sequence, the content only fills about 1/4 or less of the screen in the top left.

When I scrub through the content gets very large in the monitor, but when stopping it reverts back to small. Even though the sequences all match it won't fill the screen. I tried outputting in case it was just a glitch but the output file is imporerly framed as well. 

Using AE & Premiere v22 on Mac Mini w/ M1. It seems to happen on both the Silicon and Intel options. I've also tried it on a PC running an older version of both and the same thing happens. It worked without any issues a few times last week on the Mac Mini but it seems to be arbitray whether it will link correctly or not.
