Why does the menu in my toolbar on iOS 26 "fly" to the top of the screen?

I have a toolbar in SwiftUI where two of the buttons are Menus. When I tap on the button the menu animates out into the correct position and then it flys to the top of the screen.

When I tap on the menu button I get this.

Then within 1 second the menu flys to the top of the screen and looks like this.

My toolbar code looks like this.

.toolbar {
	ToolbarItemGroup(placement: .bottomBar) {
		Menu {
			Button { markMyLocation() } label: { Label("Mark My Location", systemImage: "location") }
			
			... (MORE BUTTONS)
			
		} label: {
			Image(systemName: "plus")
		}
		.menuOrder(.fixed)

		Spacer()
		
		Menu {
			Button { shareWithWebLink() } label: { Label("Share Map", systemImage: "square.and.arrow.up") }
			
			... (MORE BUTTONS)
			
		} label: {
			Image(systemName: "square.and.arrow.up")
		}
		.menuOrder(.fixed)
		
		Button {
			presentHikeView()
		} label: {
			Image(systemName: "figure.hiking")
		}
		
		Button {
			presentMapsView()
		} label: {
			Image(systemName: "map")
		}
		
		Spacer()
		
		
		Button {
			search()
		} label: {
			Image(systemName: "magnifyingglass")
		}
	}
}
