So on further inspection (and thanks to the nice chaps at CEDAR for a demo license), I discovered that the pagetable looks just fine, however there is an Avid issue with how switched functions are currently behaving in Expand mode. If you test out the DNSone in channel view (vertical) you should find that that Sel switch associated with the Range encoder correctly triggers the learn function. For Expand, this is mapped the same way on the 8th encoder where the Range parameter lives as you can see in the map below. This Channelstrip thread posted recently appears to be the same issue which we are currently investigating:

I will feedback once we know more. Thanks for finding this!
