SOLVED: Cubase 10.5 third party plugins not working on groups

I have to face with this weird issue. A lot of third party plugins work well on audio/instrument channels but doesn’t work on group tracks. On these tracks they appear blacked and it’s impossible to remove them.
Someone has encountered the same issue?

There was a similar issue with 10.0.50. Some people had Constrain delay compensation turned on by default. Check if it is and turn it off. By default its located in transport har left side. (orange icon when turned on)

This could be one of the reasons

Yes! That’s it! Thanks a lot
