I've got an enchanted spell turret with Touch -> Place Block with a chest behind it, and a comparator on my archwood chest to know whether it has contents. If I add or remove items manually from the chest, the comparator lights up and turns off correctly according to the presence of items or not.

However, when i activate manually my turret (or use the redstone signal from the comparator, same behaviour), the chest empties, but the comparator remains lit. Opening the chest doesn't change anything, but putting items and removing from it will refresh correctly the comparator state.
