❔ Binding method called multiple times

Hello, I'm new to MAUI.
I have face the following strange issue during development my app:

Project with a demonstration of the issue: https://github.com/archie1602/MauiTest

The application consists of two pages: MainPageMainPage and SettingsPageSettingsPage

On the SettingsPage:
I have a control witch SwitchSwitch, which I binded to the SettingsViewModel via EventToCommandBehavior from CommunityToolkit.Maui.

When switching the toggle switchtoggle switch, the OnBroadcastingToggledOnBroadcastingToggled method is started. It works fine. But:
If, for example, I return to the MainPage page and go back (again) to the SettingsPage, and then switch the slider again (switch), the method OnBroadcastingToggledOnBroadcastingToggled will be called 2 times. If I do it 5 times, then he will be called 5 times and so on...

My question is why is it called multiple times instead of one?

P.S. if I remove the binding properties IsToggled="{Binding IsBroadTogl}"IsToggled="{Binding IsBroadTogl}", then this problem disappears. But it's weird... Maybe I'm doing the wrong binding? Or is there some kind of double binding going on?

Thanks.
