Routings scheduling graph

SOLVED

Hello,

I'm having difficulties with the graph generated in Routings, Scheduling tab then Graph button in the right menu. 

Even doth my operations are all absolute successor, the graph overlaps production time and doesn't represent the actual time lenght of the routing. I,m not sure what I'm doing wrong.

thanks for your help!

Here are more information to help you understand.
