Unintended ignition

hello
I have a question, I installed 2 non-flashed sonoff modules, I use ewelink. The first one named carport works very well in my scene, it turns on at sunset and turns off at 10 pm.

For the second one named lampadaire, the slider keeps returning to the « ON » position, even though nothing allows it? When I turn it off, it goes back to « ON ». Note that it is not on line ar for the moment, it is connected behind a shelly, it is only online when the shelly turns on.

This is the last known status displayed by the Ewelink App, right? If you unplug it while it is considered on, it stays like that.
