Essential Graphics Mogrt Typeface Case Flickering Issue

I've been experiencing an issue with Mogrts that were generated in AE 22.4 and imported into Premiere 22.x. Following the update to Premiere 23.x I am seeing render glitches that are causing the case state of certain letters to flicker back and forth between upper and lower case. I can't update AE to 23.x due to the ongoing 5-frame render limitation, and I can't dowgrade Premiere since my Premiere projects can't be saved as 22.x. 

Is this a solvable issue?
