BUG: Multi band Compressor and Maximizer switching off

When working on a project, and I activate Constrain Delay Compensation button and I have inserts of Multiband Compressor and Maximizer in the insert panel of the Stereo Output, the Multiband Compressor and sometimes Maximizer switches themself off, causing me to restart Cubase 9.

But if I click again on the Constrain Delay Compensation button, they switch on.
