I'm showing the MAC address of two separate APs (IAP 105s) on the same switch port as below:
(MAST-MDF) # show mac-address-table | include 24:de:c6:c3:e5:6c
24:de:c6:c3:e5:6c Learnt 0422 GE1/0/0
24:de:c6:c3:e5:6c Learnt 0472 GE1/0/0
(MAST-MDF) # show mac-address-table | include 9c:1c:12:c9:87:2f
9c:1c:12:c9:87:2f Learnt 0472 GE1/0/0
The two APs are connected to separate ports on the same switch in a stack of three switches. Any idea why this would be and if there's a way to correct it?

What ports are the APs actually on? It is interesting to see that one of the MAC addreses is being learned on a different VLAN (422). What VLAN should they be on? It looks like a loop of some type.

Hi, Madani -
24:de:c6:c3:e5:6c is connected on port 1/0/0
9c:1c:12:c9:87:2f is connected on port 1/0/45
The APs should reside on vlan472 - vlan 422 is a user-access vlan.

Which Image version you are using in MAS ? for reconfirm, APs are directly connected to the MAS right ?
[Is my post helped you ? Give Kudos :) ]

Can you console into it?
I'm still trying to figure out how that MAC would appear on a different port. It's indicative of a loop condition and not necessarily a code issue on the MAS. One thought was that the IAP was using the other IAP as a gateway but that would require things like MESH or wifi uplink to be enabled.
