Animation Transitions, Saving?

At this page: Unity - Manual: Animation transitions, it says “You can adjust the transition between the two animation clips by dragging the start and end values of the overlap”.

When I adjust the slider bars, it never saves my transition. The preview performs the animation at the correct times that I set it to, but if I go to something else and switch back to it, it reverts to the old transition with the old times. Am I missing something on how to save it? There’s no “Apply” button or anything…

Any help would be appreciated, thank you.

You need to have an exit time if you want to save the time of the transition. otherwise the transition can occur at any moment
