Product Variable Event Totals (Impressions Tracking)

We are using the product variable to capture impressions and fire a banner impressions event. The are multiple banners on each product variable for each image request. 

The issue is that in Analytics Workspace the total for the banner impressions shows the total for the number of the calls and not the total for each banner on the product variable. For example, if 1 call is made with 3 banners in the product variable, the total for the event will show as 1 but if I break it down by each banner it will show 3.

This is causing some confusion for the users.

Is there a way to get the event totals to always equal to the total event level?
