I return to the charge and I'm sorry if this is a problem :/
 
	As you can see the slots are also displayed on the description.
 
	 
	Not duplicated on the name in the black box.
 
	 
	 
	For information, and she is 100% sure. This does not come from manually adding [0] or [1] etc next to the object name in iteminfo.lua. 
	If really no one has a solution, I'll close the topic. 
	Thanks for your help anyway.
