In MyRecipes you can add recipes to a favorite list, but it is not possible to remove a recipe from the favorite list.

To reproduce:
* Make sure you have some recipes imported
* Start MP
* Browse recipes and select one
* Press Y to add it to the favorites list
* Switch to the favorites list by pressing the favorites button in the menu
* Try to remove the recipe from the list
* I tried Y and 0, both don't work. I would expect Y to work as this would be similar to adding/removing songs from a playlist

Note: Pressing Y in the favoriteslist even adds the recipe once more to the favorite list. You see it after reopening the favorites list.
