Iphone 12 - Not receiving some android/group texts

Hola,

My iPhone 12 mini does not get some messages in group thread with android present… 

My phone has the same number twice in my cellular service line, primary and secondary. If i turn on secondary, I get the texts but cannot reply to the thread, If I turn off secondary, i dont see some of the messages at all, but can reply.

what the heck is going on, how do i reset this going forward? restart the group threads?
