Connecting to Reaper 2 channels

Hello I’m having an issue with Reaper recognizing both channels on my UR22 MKII. I can get reaper to recognize one channel but not the other. I just want to simply record 2 channels at one time. Ex - Mic is in channel 1 of my audio interface and keyboard is in channel 2 of my interface.

Reaper recognizes channel 1 and I can arm it to record however it doesn’t recognize channel 2. Any other reaper users out there with a UR22 MKII that have this problem??

Thanks for your help.
