If you update a solution that is not on the top level layer, the updated solution will not be on the top level. As noted on the following page, for other solutions besides model-driven apps, forms, and sitemap components that use the "top wins" behavior, the solution on the top level layer determines the functionality of the component.

Therefore, it can be very inconvenient for an updated solution not to be at the top level. Please consider adding functionality to help this situation.
