Reporting back. Switch came "repaired" from RMA. Both SFP ports are now in working order with both modules that I have tested and previously had issues with, with no config change on my side. Switch came back with SwOS 2.13. I was asking on some Mikrotik groups on The Internet and not ever...
Bumping this thread with the same issue as it is in OP:
Active devices such as AOC or Eth transciever will not work in SFP+1 port.
Passive DACs will work just fine.
Batch ending /250
Mikrotik Support suggested RMA basically immediately
