cant separate channels while recording

This just started, I have a ur22mkii , I record with both channel mono, now they both bleed together I can’t separate either channel , its both or nothing , juggled a lot of stuff around but no dice, any ideas???

Hi,

If you have different Mono in selected in the Input and every Mono Bus comes from different Device Port (Studio > Audio Connections > Inputs), double-check Loopback function is disabled on your Audio Device (Control Panel), please.

yes it was the loopback, why would that be default is a mystery! thanks
