Qubino Flush Shutter Motor Controller not controlling tilt

I have 5 of these Qubino devices hooked up to 5 identical motorized exterior blinds. While I’ve gone through all the configuration steps (including the mandatory steps listed in Operating modes (71) to exclude and then re-include) in order to change this to venetian mode. I seem to have everything set up, but still, when interacting with the Slat Tilt Controls in SmartThings app, it doesn’t do anything. I’ve also run the calibration on all the controllers. Any suggestions on what else to try?

Config parameters (I’ll only list anything NON-default) on all 5 devices:
71 - 1
72 - 140
73 - 0
