I cannot see the edge line

hey there, I'm new with probuilder, and working on a IMac.
When, I use the edge selector tool, there is no way i can see the actual edge I have selected.
for exemple, if I insert a edge loop, it will actualy create it, but there is no way for me to see it, except if i place my cursor right on it. I figured by watching others do, that you can have the edge lines to be always showed on the object for easier working. Do I only have miss a checkbox somewhere ? Is there a way to setup my probuilder preferences to allow me to see the edge line. I do have try to change the seleted and unselected edge color in the probuilder preference setting.

Edit : I Have installed the 4.3.1 instead of the 4.4.0, I do see the yellow line on the edge and on the loop edge.

thanks
