AC module in 3602i not detected

Question

Hello,
We have 4 3602 APs (AIR-CAP-3602I-A-K9), each with the AC module installed (AIR-RM3000AC-E-K9). We have these hooked up to Catalyst 3850s acting as the wireless LAN controller.
The AC module is not being detected on any of the APs. Everything I've read mentions that these things should be plug in play - very little needs to be done to get them working.
802.11ac is enabled on the controller:
80 MHz channels have been selected:
The 3850 supports the POE requirements to run the module.
When I do a show ap dot11 5ghz summary, I only see 40 MHz channel widths.
Also, when I console into the AP, I only see slots 0 and 1 (not 2).
This is on 4/4 APs so I'm sure I'm just missing something. Can anyone tell me what it is?

This thing will be a thing of the past since Cisco has unveiled the "universal" regulatory domain of "-UX".
