Dbdc not working on mt7615n

ok so i have been hacking/modding the bt whole home wifi disk for fun to make it a openwrt access point it has a MT7621AT cpu,16 mb of nor flash, 128 mb of ram and x2 MT7615N it is very similar to the dir 882/ dir 878 and dir 867 a1 versions here is some pics of the board and a mod i did so i can easily reprogram the flash and access serial





one of the MT7615N chips have been removed due to me shorting it out and breaking it while measuring some pins i have 2 replacements but i have no soldering stencil so i am waiting for some solder balls to try and use but to my question I'm having a problem enabling dbdc I'm using firmware 22.03.2 compiled for the dlink dir 878a1 when i try to enable dbdc i get this error

and it doesn't create the other phy here is the iw phy output after trying to enable dbdc

could this be because the firmware is compiled for 2 MT7615N's and one isnt detected so it wont work or is it something else
