Metronome Not Outputting To USB Mix on Most Recent Firmware (4.10.25)

Preview Sound is set to Output 1&2 and is outputting to USBmix. Metronome set to Output 1 is not outputting to USB Mix. The same is true of any of the potential outputs for the Metronome. I am curious if this is a glitch or user error?

My workaround is creating my own 1/4 metronome but is frustrating. Can anyone else recreate this glitch on the most recent firmware or is this just me?
