AP active shows 80Mhz channels BSS-table shows 40Mhz channels

I have a strange scenario here, not sure what's the cause of it and if it messes anything up.

Problem is that "show ap active" command shows ap/channels with E flag. But when checking bss-table I can clearly see that the APs are using 40Mhz channels for the BSS (+/- sign after channel), and all clients connected are connected on 40 Mhz. 

To me it seems like AP has 80Mhz channels enabled but all SSIDs are using 40 Mhz channels for some reason. 

Also see output from "show ap arm history" which i find strange, there is a airmatch entry even though the controller is in standalone mode.

Running Aruba7030

Has anyone seen similar behaviours that might be able to shed some light into this? The radio profile set to 40Mhz channels.

How’s the RF Profile / ARM profile configured ?
How’s the HT SSID Profile configured ?
