Motu 2 Audio Interface will not use frd calibration files

White making frequency response measurements of my speakers I noticed that the high frequency rolloff was excessive. It was 16-25dB down from 1oKHz to 20KHz. The calibration frd was working fine with my ancient Mobile Pre audio interface (which finally died) and REW which I confirmed by loading some older rew files. I have confirmed that the calibration file is loaded by clicking the tab on the measure page. I have added the calibration file to every input. The Motu 2 is connected to usb-c port. I checked the devices in device manager and all looked fine. I have attached some screen shots of the REW preferences screens.

I don't think REW supports simultaneous multichannel measurements.
