I ran into a similar issue where the bridge group name did not match on the subordinate APs. Link on the topic below:

Hello,

Not having a mesh option in a WLAN with subordinate APs does not sound right to me. Mesh is required for subordination, unless setting each as a single primary WLAN. Can you share a screenshot of the screen where the mesh option should be available?

hi,

Sorry for confusion. All the APs in the network have a Wired Uplink. The APs in the network are Primary capable. One among them is serving  as a Primary AP.

 

 

 

No worries. In the screenshot titled wifi.png, if you click the action button to the left of each AP, you'll be able to view the bridge group name. Ensuring they were all the same, solved the issue I was experiencing. 

Here is a more general troubleshooting document, though it doesn't reference your symptoms exactly:
