Cubase 10.5 - FX Chain Pre-set Issues - Plugin's visible but greyed out when others seem work?

When starting a new project, I tired to open saved FX Chain inserts on my channel strips and all have loaded - though some plugins appear to be greyed out and cant be opened and don’t respond to anything.

I can’t seem to make sense of it as the same plugins work when used in a pre-set FX Chain uploads on a different channel strips? Does anyone know the fix here?

I have tried opening up the same plugin’s on a blank channel strip and again strangely the same plugins grey out. Its very annoying!

I’m using Cubase 10.5 with Fab Filter, Izotope Ozone 9 and Slate Digital Plugin’s

Any help would be appreciated.


Make sure the Constrain Delay Compensation is not enabled in the project, please.

OMG you are amazing! Thank you so much! It worked!!
