Both MPPT defined as slave

Hi!

I just realized both my RS Smartsolar MPPT 450/100 are listed as "slave" (BMS controlled).
Shouldn't there be a master and a slave?
(Trying to find out why my MPPTs are always limited when batteries are full - I have DC Grid Feed-In enabled)

MPPTs are controlled by the BMS (ext. strut. & BMS), this won't recognise grid feed in. Not sure how to change. Hopefully one of the others can help.
