Some plugins not working in stereo out bus in mixconsole

Nuendo
1

I just upgraded to Nuendo 11 from 6. In 6, when I was ready to mix, all my plugins were available in the final stereo output channel. In 11 , some will not function and cannot even be removed. This cannot be right. What am I doing wrong?

turn off “Constrain delay compensation” or change the threshold for it

First of all, be sure that all your plugins are up-to-date.
Nuendo 6 is stone-age technology, so there is a fair chance that a number of plugins are also outdated.

Secondly, you are aware that VST2 plugins are not supported anymore!?

Thanks to all! Looks like turning off "constrain delay compensation " did the trick!
