RB4011iGS+5HacQ2HnD-IN + 7.1rc6 : /system/leds breaks export/import

Starting with rc5/6, default configuration includes the following leds config :

/system leds
add interface=wlan2 leds=wlan2_signal1-led,wlan2_signal2-led,wlan2_signal3-led,wlan2_signal4-led,wlan2_signal5-led type=wireless-signal-strength
add interface=wlan2 leds=wlan2_tx-led type=interface-transmit
add interface=wlan2 leds=wlan2_rx-led type=interface-receive

These instructions are present even with “no-default=yes”.

Problem, a complete “export” generated this way :

/export show-sensitive terse file=complete-export.rsc

fails through:

/system/reset-configuration no-defaults=yes skip-backup=yes keep-users=yes run-after-reset=complete-export.rsc

because the exported /system/leds lines conflict with default ones.

Hello,
Please config from different HW is better make from Files and backup, or from terminal export “file.rsc” ?
If config is from pppoe, is it possible make it from bridge to router it?
Soory, but I don’t know, where to ask.
Thank you.
