Stack Size Controller + Chest Stacks problem

Good afternoon! To be honest, I don't know who to write to and which plugin fails. It costs two of the above plugins .

The size of the player's inventory is set to 10,000.
The dimensions in the box are set to 50000.

I really count on your help!

 

I understand that no one is engaged in the plugin?
