wifi scan disabling the broadcast ssid

I was testing the wireless scan and found a problem.

using version 6.37.1

After doing wireless scan :
/interface wireless scan wlan1 duration=10s save-file=wireless-scan

the device stops broadcasting the SSID, if I disable/enable the wlan1 on webfig interface it returns, or if I just enable by command line it also returns
/interface wireless set wlan1 disabled=no

Anyone else can confirm this problem ? I have tested with two different devices and got same behaviour.

Try background scan.
