rstp Problem on hpe 1920g and some comnet industrial switches

Hello,

I am going a bit crazy over a network, i have 2 hp 1920g poe switches, between them about 9 comnet industrial switches on two lines forming a loop, so i need rstp to work to open loop and keep redundancy active, if i assign on an hp the role ov root bridge the comnet seems to see it as root, but on hp ports i see a strange behaviour as here

 it seems the bpdu received from comnet is wrong for hp

do you have any suggestions to fix this?

thank you very much
