UR22 mkII - Mic/Line 2 doesnt work

Hi Guys,

My Mic/Line 2 input doesnt work. It acts like it doesnt exist. Line 1 is fine, I am using it for my guitar but I would like to connect my Mic to Line 2.
Connecting guitar only to Line 2 doesnt work either.
Do you happen to know what might be causing this issue, please?
Am I supposed to see two Steinberg UR22 inputs in my Recording devices?
