Strange Playback Imbalance Issue

Hi friends.

On playback, the currently selected staff/instrument plays back much louder than all of the other staves/instruments in the project. This also happens when multiple staves are selected; whichever staff was the first one selected, before selecting additional staves, is louder.

Playback engine is Note Performer 4.5.1. I’ve messaged NP about it and waiting to hear back, just in case it might be a NP issue.

Does anyone have some insight on this, or has anyone else experienced this? Thanks!
