There's an error I can't fix

What I want it to be exactly as follows;
1- There will be many different papers in my game and there will be different texts on top of them.
2- Each paper should be opened and closed when we read the q key and press the q key again. A separate triggerbox is assigned to each paper.
3- Separate widgets have been created for each paper.
4- Variables (boolean) are created to distinguish whether the paper is readable or unreadable.
5- Wp_Oku makes it say “press Q” when it comes over the papers.
6- I am currently adding the blueprint sample created for 1 paper as a picture. You can also see the variables that have been added.

Smooth employees: The papers can be opened and closed with the q key, but we can only do this once. Then we have to get away from the triggerbox and go back into it.

Problem: After reading a paper in the game, when trying to read other papers, it can show the content of another paper. It doesn’t always happen sometimes it happens.
