UR22 Right Monitor Is Louder Than Left Monitor

Hello,

I’m having an issue with pretty significant volume differences between my right and left Yamaha HS5 monitors.
I think my Steinberg UR22 interface may be the source of the problem.

Upon noticing the problem I shutdown my PC and unplugged/re-plugged the cables but still could hear the difference in volume.
I later swapped monitors and the problem still remained.
I also swapped my Steinberg UR22 interface with my much older PreSonus AudioBox USB 2x2 and the problem disappeared.
So that’s why I’m fairly certain that there’s something wrong with my Steinberg UR22 interface.

Any help would be appreciated.

Thank you.
