CJA- Attribution for adobe campaign reporting

I'm having an issue with assigning credit to campaigns for a conversion metric. We want to see which campaigns result in a client login/registration within 2 days of it being sent out. 

The segment I created is assigning credit to every campaign a person sees, regardless of whether that individual campaign was responsible for the conversion. For example, if Jim Smith saw Campaign A on March 1- converted to login on this one, Campaign B on April 4 (no login), and Campaign C on April 15 (no login), it's showing that all three campaigns are credited with the "action complete" when that isn't actually the case. I only want it to show that Campaign A receives credit for conversion, not the other two. 

Is there a way to handle this in CJA?
