Lead Owner Problem - A simple question

Lead Owner Problem - A simple question

Hello All,

It is my first question on this help forum and it'll be a simple one i guess :)

The basic idea for me was to monitor on a weekly basis the ability of my salesmen to create leads and turn them into opportunities.

To do so i'm editing the L eads to Potentiel Drop out Analysis and i've changed the first variable which is lead source to Lead Owner.

The output looks like this : 


It is the french version so "Tous" means "ALL"

The problem is that Paul is not my only salesman and i only get his figuresinto the table...
There is no filter applied to Lead Owner, here is a quick view of how the table was parametered :








Does anyone have an idea of how i could solve this problem ?
