UNI-II Lower bands won't enable on 1/4 NSM-5

I have 4 NSM-5 radios at a site. Three of the four have all the UNI bands available. On the fourth the neither the "Enable UNI-II rules" prompt nor the lower channels are available..

 

All four radios are on 6.1.8. This one has firmware load XM.v6.1.8-cs.32774.180921.1533

In order to activate DFS bands on XM devices, you need to downgrade the radios to 5.5.10.

 

There were two sets of UNII/DFS grants and XM devices need to be activated under the older grant.
