When using UMG and enabling advanced options then deselecting and reselecting the asset can cause issues with the scrollbar length and cause some options to be initially cut off. The scrollbar then adjusts to the expected size. The issue is caused with the initial reselection of the asset. This issue is best reproduced when the details panel is on the left-hand side.
Result: Notice that even though the Events section is expanded, the section is empty and the scroll bar cannot be scrolled and further down
Expected Result: The Events graph info can still be seen or scrolled to
Workaround: Scroll the bar up then down and the Events section will be visible again
