AE MOGRT + Responsive Design in Premiere pro issues: playback and INTRO/OUTRO

I have created some lower3rds on AE, applied the Responsive Design feature to INTRO/OUTRO and imported them as MOGRT into Premiere. I had no problems editing the text neither with the INTRO/OUTRO until I save the project. On the next day, when I opended it, the caos had taken place: playback/render issues and loss of the INTRO/OUTRO of almost all lower3rds. It was impossible to recover it and I needed to redo all in AE.

It has also happened with other two colegues using other two computers. We all use the 2020 version of both, AE and Premiere.

What is happening?
