After update to 6.42.6 - Netwatch on Up and on Down when running /system script run not work

After update a firmware and RBOS to last version - my failover scenario stopped working.

I use netwatch to watch ping to 1.1.1.1.
I have a firewall rule that block ping to 1.1.1.1 from wan-2 (it is pingly only from wan-1)..

On UP I run: /system script run wan1-up
On Down I run: /system script run wan1-down

The problem:
When I run scripts manualy from system → scripts everythings work correctly, but it is not work when status on netwatch is changed from up to down and from down to up.

My router:
routerboard: yes
board-name: hAP ac
model: RouterBOARD 962UiGS-5HacT2HnT
factory-firmware: 3.31
current-firmware: 6.42.6
upgrade-firmware: 6.42.6

Any ideas?
