Can also confirm. I helped a team diagnose this issue. The symptom was that it would bind up when going one direction.
As others have said would suggest a CIM mounting style similar to this

Where there are 2 holes for each distinct gearing option. Also, since the clearance hole for the bore is not actually a locating feature any more could you make it big enough to slip the 14T pinion through. This way it can be pre-installed on the CIM before assembly. One last request would be to separate the CIM mounting bolts from the standoff mounting bolts. That would make it much easier to take the CIMs off without the entire thing falling apart.
