How to look up a BSSID on fortiwifi 60 C

We have  a store that is showing 3 ssid named xpress.  two of the ssid ar 2.4 ghz and the other is 5 ghz . One of the ssid manufacture is sparklan  communications inc   with a Bssid  mac of   00-0E-8E-40-3A-1A . the other two  xpress ssid are fortinet as the manufacture . I have pulled all the mac addresses from the fortinet 60 c . None of them match  this bssid above. I have pulled my hair out looking through the fortinet 60 c trying to find BSSid Macs to see if this mac above matches. 

Can someone please tell me how to pull the bssids please much replies would be appreciated .
