Cubase 10.5 not reading automation on VSTi (VSL synchron)

I am having an issue with cc automation on one of my vstis. For some reason, it is not reading the expression and modulation automation and sometimes the expression map stops working. It only works when I reload the instrument, but stops after a seemingly random amount of time. I don’t have any overlapping midi parts. I also dont have an automation controller that can be causing this, I have not had this issue in any other projects. Please see youtube link.

Any ideas?

Thank you
