Hello,
I have the same problem, the plugin works correctly when an item is added to the cart, but when two items (which should hide the plugin) for extra data that should not appear appear are .
For example , item A need date , Article B not .
If you buy an item B does not appear date , correct.
If you buy two articles B does appear date , error.
If we buy article A does appear date.
Thank you
