Previewing MIDI Loops in right zone

In Cubase 11…0.10, when I preview MIDI loops in the right zone Media tab, they seem to ignore the preview level set at the bottom and just blast out at full volume. Audio loops and files work as expected, volume controlled by the level slider.

Doing the same thing in the Media Bay window works as expected - MIDI loop preview volumes are controlled by the preview slider just like all other files.

Am I missing something here or can anyone confirm this behavior is a bug?

Thanks
Richard
