UR44 Clock/Sync Issue

I have a fairly new UR44. Running Nuendo 8. Have what sounds like clock/sync popping/clicking/ticking on everything I record with it. The ticks are not there when monitoring the unit in “Direct Monitoring” mode or using it as a stand alone mixer. They appear across all channels being recorded.
