Campaign Response Enity mapping to Lead

Hello,

When converting a Campaign Response to a Lead, I can see that the first name, last name, and company name maps over to the Lead. How can make more fields from the Campaign Response entity to map to the Lead enity?

Here's what i tried, but no success:

1. Under the campaign Response Entity, added the 1:N relationship of Campaign Respons to Lead.
2. In the Mappings, I added source fields from the Campaign Response to the Lead.

When I convert the campaign response to a lead, none of those fields mapped across.

What else am I missing?
