Reverence 7.1 mode mutes channel after import

I think I may have found a bug in Reverence.

I am using it in 7.1 music format. When I load the 7.1 channel impulse the left rear (channel 5) mutes. Reverence does not render that channel for some reason. The meter is also muted. I can close the project, reload it and all channels play back fine.
Once you import another impulse channel 5 is again muted.

I did try this in 5.1 surround and everything checks out fine. Importing new files always works.

The routing seems to be fine through the FX channel after muting Reverence so it leads me to believe that it is in the plugin itself.

I even tried disabling “suspend VST3 plug-in processing when no audio signals are received” but that did not help.

Anyone else experiencing this?
