Changing Interface's MAC

Found a thread similar to something I have been chasing for a day or two...

https://community.netgear.com/t5/Managed-Switches/Changing-Port-MAC-addresses/td-p/1355539

I've spent a couple of days trying to trace down what WireShark was reporting as a Layer2 Loop (RLDP), what I found was two of my netgear switches are reporting the others mac address on multiple ports,  this kind of aligns with the previous thread I found above. 

My first switch is configured with 6 different vlans used for a watchguard firecluster and has six cables going to the next netgear switch for their respective vlans for distribution. Everything is fine as I am not able to find any loops other than the one Wireshark is falsely reporting as a loop. When I clear the address table on switch two, I can see the mac for switch one come back on all six ports, why wouldn't netgear use a different interface mac so this is avoided? All of the other switches like Dell and Extreme I have do. Is there a way to cure this?
