Short description of error
Missing EasingType options in context menu on the Dopesheet
Exact steps for others to reproduce the error
If you can select Easing Mode in the DopeSheet, then you should also be able to select the associated Easing Type.
The workaround requires both the DopeSheet and GraphEditor at the same time. Not intuitive.
