Why confidence value is infinity?

I found some problem in FP-Growth operator. 
The FP-growth has a parameter named "min items per itemset". It is set default value as 1.
In my process  I set  the value as greater than 1, in result I received some rules that confidence value is infinity.
I did so because I didn't need the itemsets of size 1. 
I am sure there is no relation between confidence and that parameter value.
I think it might be bug.
I hope rapidminer developer to verify and to improve the problem.
thanks.

[update 9 Mar 2020: Engineering has taken this idea and is working on implementation] PM has determined that the best option is to add another min items per itemset parameter to the Create Association Rules operator. It's a feature request so please upvote. RM-3999
