Show & Hide Elements on Click (only works with two clicks in the trigger)

Hello! I followed the youtube tutorial “Show & Hide Elements on Click” and everything works fine except for one thing: I need to click twice in the triggers ( Text and (X)Text ) to show and hide the info of each project in the feed.

Could you please help me with this? It’s the only problem that holds me from finish my website. Any help would be amazing.
