Accordion Flash Issue on FAQ Menu

Hey everyone!

I’m encountering an issue with my website’s accordion FAQ menu. Whenever I collapse an item, there’s a brief flash showing the entire expanded FAQ before it returns to normal.

Has anyone faced a similar issue or could provide insights into what might be causing this? Any advice on how to resolve it would be greatly appreciated.

Thanks in advance for your help!
