I have a Tabbar and within there is Tab that contain two shell content. When I navigate between tab and tab bar item, everything is fine. However, if I click on a ticket on navigate to the ticket page, when I press on back and return to the main page, the calendar tab disappear.

This is my AppShell

<ShellItem Route="LoginPage">
        <ShellContent ContentTemplate="{DataTemplate local:LoginPage}"
                      Shell.FlyoutBehavior="Disabled"
                      Shell.NavBarIsVisible="False"/>
    </ShellItem>


    <TabBar Shell.FlyoutBehavior="Disabled"
            Shell.NavBarIsVisible="False"
            Route="MainTabBar">

        <Tab Title="Intervention"
             Shell.BackgroundColor="White"
             Shell.UnselectedColor="Black"
             Shell.ForegroundColor="#85f189"
             Route="InterventionTab"
             Icon="maintenance">

            <ShellContent Title="Aujourd'hui"
                          ContentTemplate="{DataTemplate pages:HomePage}"
                          Route="HomePage"/>

            <ShellContent Title="Calendrier"
                          ContentTemplate="{DataTemplate pages:CalendarPage}"
                          Route="CalendarPage"/>
        </Tab>

        <ShellContent ContentTemplate="{DataTemplate pages:MapPage}"
                      Route="MapPage"
                      Title="Carte"
                      Icon="map"/>

         <ShellContent ContentTemplate="{DataTemplate pages:ProfilePage}"
                       Route="ProfilePage"
                       Title="Profile"
                       Icon="profile"/>
    </TabBar>

When I log in, the following is tiggered

await Shell.Current.GoToAsync($"//MainTabBar/{nameof(HomePage)}?Technician={UserName}");

When I click on a ticket within the Homepage, the following is trigerred

await Shell.Current.GoToAsync($"InterventionTab/{nameof(TicketPage)}?TicketID={SelectedTicket.Id}", false);
