Vizlib Venn diagram Circle intersect and tooltip issue

Hi Team,

I am facing two types of issue with Venn diagram 

1. intersection with four circles is not happening:

Am using a field with 4 different values and a measure in that only three circles are getting intersected. But I need the intersection point for 4 circles. 

To my analysis and knowledge if the intersection value is too low compared with other intersects it is not intersecting. But in the tool tip I can see the intersect of four and the value for that.

2. Tooltip values:

on the tooltip I can see one value if i hove on any intersect point, but for the same intersection it is showing less value when I hover some where on the venn diagram.
