Need help Keitaro reporting

I've been testing keitaro for a week now, wondering anyone who uses keitaro could shed some light how to read their reporting

I have Stream 1: Lander 1 -> 3 offer rotating



There is 1 row in the offer column that is blank, i asked the support they said it is because people clicking on the lander but not through to the offer

isn't it supposed to be
-. 100 people click on lander 1 and 10 people click through to the offer 1 = 10% ctr and for example +10% ROI
-. 100 people click on lander 1 and 5 people click through to the offer 2 = 5% ctr
-. 100 people click on lander 1 and 3 people click through to the offer 3 = 3% ctr

so question is how do i know which offer is converting when people that don't click through to the offer are group in 1 row? and the roi reporting is separated?

Any way
