Redmi 3 ido, two devices with the same MAC address

Hi, i have two the same devices, ido, with mk90.0-ido-200220-release, both have the same MAC address, so they can not connect to the same wi-fi in the same time. One must be disconnected when the second is connected. Tried also mk10, lineage os, aosip, the same problem. Only DotOs 3.1.1 works good in this way.
