Shift help

I have someone trying to create an overnight shift during the week only form-f, so they would be on-call 12:01AM Monday morning until 8AM, then 5PM until 8AM the next day. How do I get it to stop at Midnight on Friday night so it doesn’t go into Saturday morning until 8. I tried setting it to only weekdays but it still runs into Saturdays?

Or do you have to setup 2 schedules?
