Don't store ListView Elements in TinyDB.

They are hard to reconstruct as their primary ingredients, like turning apple pie back into apples, flour, and butter.

Instead, keep a list of dictionaries under your TinyDB tag, and generate a parallel list of Elements from it for use in a ListView. Use the SelectionIndex as the index into the list of dictionaries to get access to the selected dictionary with the keys,values you want to show in your Labels.
