Help no Midi clock even with persist but Tap works fine - MC3 3.9.7

Any help is appreciated… I’m unable to get the MC3 to output midi clock unless started by tap even with midi clock persist turned on. Though clock doesn’t show up on the Morningstar midi monitor, an external midi monitor shows only sysex messages when pushing a switch set to midi clock while tap starts it running. I hope I’m not missing anything obvious. Thanks
