After Effects graphics aliasing severely in premiere

I've been experiencing an issue where any time I import graphics into premiere from after effects, severe aliasing will occur. The graphics (usually animated lower thirds in my case) will look fine on export, and they'll look fine when I initially bring them into my timeline, but if I save, close, and reopen the premiere project at all, they'll get chewed up. I end up having to re-export all of my graphics from after effects to fix it every time I reopen and close the premiere file, which obviously doesn't work for me. I'm including a before and after here:

This also happens if I downsize my graphics at all.  I'm up to date running version 24.2.1 for AE and Premiere. I've tried uninstalling and reinstalling, and this has been an issue since before the previous update. Exporting to quicktime MOV, formatting that's always worked for me before. And again, the graphics look completely fine at first export, so while formatting could be causing the bug, I don't think the initial export format is where I've gone wrong. Completely fed up! Please, any advice at all would be great.
