Expected behavior 1. An item should close only by clicking on the header 2. Clicking an item to open it for the first time does not open the item 3. The opening and closing effect doesn't always work

Actual behavior 1. An item closes by pressing the body 2. The item opens only from the second time on 3.I did 3 items, the first two opening and closing effect works but the third didn't (Even if I change the order between the items, the third one still doesn't work)
