Import bridge related configuration in ROS6

RouterOS General
1

I restored a configuration file using the ‘export’ command.
I am trying to import it back using the System → Reset Configuration functionality with ‘No Default Configuration’ checked and selecting the respective .rsc config file.

The configuration is bridging the wlan1 and the ether1 interfaces of a GrooveA 52ac (v6.45.9).
I read similar previous posts in the forum, I also tried to write it as
/interface bridge {
port add bridge=bridge1 interface=wlan1;
port add bridge=bridge1 interface=ether1;
}
and also disconnecting my Ethernet cable connection immediately after pressing the ‘Reset Configuration’ button.

In all cases the restored configuration is missing the ether1 from the bridge (wlan1 is added)
Is there anything else to try so as not needing to manually connect and add the ether1 to the bridge after the restore (prefer to avoid the binary backup/restore for portability reasons for multiple Groove configuration)?

Place :delay 1m at the beginning of the
.rsc file to be imported this way. The interfaces are most likely not detected yet while the script attempts to use them. The reset-configuration command causes a restart so the device boots from scratch.
