Transition graph changes are discarded

I want a very short transition from one animation to another so I am tweaking this using the transition graph. The problem is, my tweaks are discarded when I play, save and close, etc. Here are screenshots:

Before I start

My changes

Right when I press play

How can I get my changes to stick?

you need an exit time to tweaks your transition like you want. When there is no exit time the transition is free to start as soon as all other condition are meet.

Also the range cursor change when you don;t have an exit time, it change from a small eye to an arrow
