[BUG] Analytics overview not working correctly

[JaanikaTalvistu]

Bug description:
When analytics overview is changed in the analytics module, the field behaviour is inconsistent. Card filters move around randomly sometimes when clicking/dragging. Cards are automatically unchecked when moved.

Expected behavior:
Card filters stay on their place or move one space forward when other cards are moved or swapped out (when swapping then one space backwards is applied).

Logic was initially faulty, now looks better.
Issue was that it was updating index on one element, and others keep their index makig it impossible to keep order as more than one element try to get same spot in the list, causing chaos, currently i am using sorted array indexes for initial logic and should keep ordering corect.
