Too many blueprints when researching

have a problem on my server and I need help urgently, whenever someone studies some item in the research table comes many blueprints, 30/40/10000, already came up to 5 million, can someone tell me how to fix it?

 

What pluggins are you running on your server ?

I think xp control has something to do with it, But im not sure

 

I did a topic and no one helped me, sorry for the double, but I really need help, when the players on my server use the search table comes 99999999 blueprints, which allows them to duplicate items, could anyone help me? I need urgently

 

It sounds like this might be an issue from the stacking plugin. Can you provide us with a little more detail. What plugins do you use? and can you show us pictures of the issue?
