Studio One will not arm recording

I just bought Studio One 3 Artist as well as a Focusrite 18i8 gen 2 and both are installed per specs (focusrite first). The problem I am having is that I am not able to arm the recording on the track. I have checked other questions and have tried doing what they suggested. I am logged in as an Admin and the location of saved files has necessary permissions and it appears that when I do the song setup that I have the I/O correct. When I have the "Song Setup" open my L chael I am trying to use for vocals is getting a signal and it is also showing a signal when I click the monitor button on the track. Am I missing something?

When do I need to leave the input box open in Song Setup and when do I need to add the Mono "M" button? I have tried both ways and I still don't get access to the record function. Please help!

I am using an HP Pavilion dv7 laptop with proper specs (as far as I can tell) and with windows 10. I am using a focusrite 18i8 with the Studio One Artist. What am I missing?
