This might be because the DIM value is too low.
Dim is designed to reduce overall monitor/speaker level when Talkback is engaged so to prevent feedback and disturbing echo from the Control Room. By default, the dim level is set very low, so try to raise that, either by using the so labeled dial in the VST Connect plugin, or the linked knob in the Control Room/Monitor section.
Other than that, there appears to be no reason why you shouldn’t hear Performer during pause.
