Lot's of broken widgets on development phone

On the phone on which I develop this app, I see these broken widgets:

Somehow, they also cannot be removed.
I think this is roughly the error we had when first adding them.

The idea that I have here is that the app when re-installed, needs to implement another hook to re-instate the widgets. It is unclear to me if that behavior will also happen if a user updates to a later version.
