MOGRT Replace Media breaks when MOGRTs are used in Premiere

Hi All,

I work in After Effects to make MOGRTs for every video series my company produces. Before the latest update, I could drag and drop photos or logos from my timeline to the AE Essential Graphics panel, making them replaceable assets for our editors to update for each video. All they had to do was click the hamburger menu in Premiere and select "Replace from Finder." Now, the option to do so (or to do anything with the replaceable file) is greyed out. 

To make them work again, I cleared all properties, recreated them, and reexported the MOGRTs in the latest version of AE. The issue persists. I currently have about three templates and ten files within those templates that are affected. We produce 5-10 videos a month affected by this change. Would love to fix the issue quickly so that I can continue using and building out our CC libraries. Thanks!
