CJ4 question on how to enter runway for approach information on FMS

On a career mission I had the RNAV B approach with circling minimums to airport KAQW Since the approach did not specify a runway, the FMS Perf-Approach page did not have the runway pre-loaded. When I tried to enter the runway info into the approach page to get my v-speeds, I got “Key Not Active”. Normally, when the approach is to a specific runway, the runway field is already loaded when I open the page.

How do I enter the runway info in this situation so I can get the approach speeds? Appreciate any help!
