Normally my MEP 2016 KF area looks like this for selected objects that have KFs applied.
In this example I might click the arrow to the left of 'Image size/position' in order to see its components:
And then I'll click again to close it to the original familiar compact display.
But if I then select any other object on the timeline with KFs, the display is always the expanded one.
Have I missed a setting which controls that behaviour, as it seems incorrect to me?
