cloudguard interface _rename issue

[Fareed_Farooqu1]

Hi

We are deploying cloudguard R80.20 in Azure as per sk110194 and are noticing extra interfaces with '_rename' in them. Instead of eth0 and eth1 we see total of 4 interfaces

eth0 

eth1

eth2_rename

eth3_rename

Output of  ifconfig  is

ifconfig -a | grep -v grep | grep HWaddr | awk '{print $1,$5}'

eth0 00:0D:3A:7E:82:B6                      state -on
eth1 00:0D:3A:7E:87:40                       state -on
eth2_rename 00:0D:3A:7E:87:40       state -on
eth3_rename 00:0D:3A:7E:82:B6       state -off

Has anyone came across this issue? 

R80.10 does not have this issue.

Thanks
