IP Assignment with Aerohive APs (Using wrong VLAN)

We have 8 locations all using Aerohive APs with the same configurations across the board, but one of our locations is assigning IP addresses based on the native trunk vlan assigned to the port the APs are connected to (AFAIK). The switch ports for the APs are setup as trunk ports with the VLANs being used in our SSIDs as trunk allowed VLANs. None of our SSIDs are configured to use the VLAN that the clients at this location are being assigned. How do I troubleshoot this? I have checked all the locations to make sure the switch ports were also the same configuration.
