Automation problems when migrating from cubase 9.5 to 10

Hello !
After installing Cubase 10, I opened projects I made with Cubase 9.5, and it seems like I lost all automation on String Ensemble, Brass ensemble, Session strings pro 2 etc…
Don’t want to start things all over again after every update…
Some of you encountered the same problem ? Do you have any solutions ?
Thank you !
