Form Submission Via Campaign Analysis report does not give only Campaign specific results

Problem Scenario:

Let's say I have a Form attached to different 3 Campaigns. Let's call them Campaign A, Campaign B and Campaign C.

Now my overall form submission is 100 (irrespective of which campaign it is coming from or even independent form submission). From this 100, 20 form submission come from Campaign A.

When I run  the Campaign Analysis Report for Campaign A , the form submission however shows 100 instead of 20. The 80 remaining contacts are not even part of my campaign in the first place. i asked on My Oracle support and they had no soultion to this. It is quite disappointing as we had this functionality in Classic Insight but seems to have been let go now.
