CHR recreates ethernet adapter after live migration in Hyper-V cluster

Hello.
I’ve got Hyper-V cluster with CHR intalled on it.
When CHR router migrates between hosts in cluster it recreate ethernet adapters.
When it happens I loose names and comments of ethernet adapters, bindings of ip addresses, interface list bindings, etc. Else sometimes ethernet adapter increese their numbers (ether1, ether2, ether3, etc).
Is reason in my virtual machine wrong configuration or it is a bug of ROS?

I want to note that Generation 1 VM was created as described here https://wiki.mikrotik.com/wiki/Manual:CHR_Hyper-V_installation
Latest ROS version 6.42.5 is installed.
