Face selection menu issue when back from Watch Face settings view (InstinctCrossover)

Dear community,

I'm facing a drawing issue with the watch face selection menu. I've developed a simple face for the Instinct Crossover. I'm in the process of implementing the settings view.

My issue is when I press back from the settings view, the face watch menu that displays the Apply / Customize option is not re-drawn.

The full process is the following:

I long press Menu button, and select Watch Face.
I navigate through the Faces to select mine.
The menu with Apply / Customize appears with a press on Start button. I select Customize.
My settings view pushes in.
I press back, and my setting view pop out. My face is drawn, but the menu with Apply / Customize is not drawn. But still active because I have to blindly navigate up and select to apply the settings and exit.

It is not something I can see with the simulator unfortunately.
I can take a video of the behavior if it can help to understand.

My code is here  https://github.com/pierre-muth/HandAvoidance/tree/main/source

Should I add something more in my settings view delegate ? in :

public function onBack() as Boolean {
        WatchUi.popView(WatchUi.SLIDE_RIGHT);
        return true;
}

Thanks for reading!
