Export config renames interfaces

Hi,

I have a strange issue when I export the config the Interfaces are being renamed;

set [ find default-name=ether5 ] comment="WAN1" name=ether1
set [ find default-name=ether6 ] comment="WAN2" name=ether2
set [ find default-name=ether7 ] comment="WAN3" name=ether3
set [ find default-name=ether8 ] comment="WAN4" name=ether4
set [ find default-name=ether1 ] name=ether5
set [ find default-name=ether2 ] name=ether6
set [ find default-name=ether3 ] comment="LAN Uplink" name=ether7
set [ find default-name=ether4 ] name=ether8

Thanks in advanced.

Are you trying to change the name of ether5 to ether1 while there is already existing ether5 interface name…? What sense does it have?
