MediaTek MT7613BE multiple networks potential bug

I just got my Archer A6 v3, and I am experiencing trouble with the 5GHz radio. Whenever I try to create more than one network, all networks on the 5GHz radio fail to start. This does not happen with the 2.4 GHz radio. Is this a bug, or simply a hardware limitation?

are the 5ghz networks all on the same channel ?

Yes, the channels on the network confígs follow each other and stay in sync

Could you paste you /etc/config/wireless config here? (be aware: hide your ssid password)

Here it is

Any idea what could be causing this?
