Thank you all for your prompt reply, it was a glitch in the matrix as I needed to restart the computer and empty the temp files and delete the cache from Premiere pro menus.
How weird is that? Sorry! I have not seen an issue like this before. Is it possible to share your project file from After Effects? I can do a sanity check for you if you like.
I am not sure what to suggest other than a workaround. I would be exporting a file directly from After Effects and importing it into Premiere Pro, and seeing if that might work for now. I'll discuss this with the team and see what they say.
Thanks, Kevin
