3850 vlan?

I got a brand new 3850 running 16.3.5b and one port just won't take a vlan to it. Never shows in 'show vlan' no matter what I do. Never seen this before. I have HA PANs upstream and failover wasn't working and I couldn't figure out why. Port 45 would come up but wouldn't pass any traffic. I configured another port (gi1/0/37) in vlan20 and moved the PA to it and it works now.

Has anyone seen this before?

20 fw-and-stuff active Gi1/0/29, Gi1/0/30, Gi1/0/37, Gi1/0/39, Gi1/0/40, Gi1/0/43, Gi1/0/46 interface GigabitEthernet1/0/45 description ###firewalls and stuff### switchport access vlan 20 switchport mode access end
