The issue being addressed is that when a user added key-value items into a map-like tag and then removed only one item, it would delete all the items in the map.

The development team has fixed this issue and now when a user removes one item from a map, it will only delete that specific item and not all the items in the map. This ensures that users have greater control over the items in their maps and can make changes to them without accidentally deleting all the items.
