yugutou According to Nate, displaying the previous curve when there is no following key was an intentional change made so that users would not need to reselect the previous key.
However, as in the example you provided, this behavior can be confusing when a translate key has a following key but a scale key does not. We will therefore change this in a future version so that, when multiple keys are selected, only the curves between the selected keys and their following keys can be edited.
