Andrdoi: Attempt to fix a number of issues querying containers. Always returning nullptr from the query functions made it always fail. Varaibles were incorrectly named and I had incorrectly assumed the SparseBooleanArray only returned checked items. This is not the case, it only returns items that were changed. So we now take this array and create a copy but only including the items that are checked so the code works as intended.
