CRJ + CH Throttle USB

Just acquired the CRJ’s yesterday and having some problems with throttle power. Specifically, the full range of motion on the CH Throttle only converts to about 2/3’s of the CRJ’s power settings. Basically, I’m limited to IDLE & TOGA. This hasn’t happened while flying any other aircraft. Advice would be appreciated.
TIA!

Did you try the Throttle Calibration screen in the EFB?

Yes I did though given the complexity of this aircraft perhaps I botched it.
