After changing the view to columns (by going through Right click < Create Dialogue < View Options < Columns) the Sound Wave Action menu will close out automatically before any options can be selected when opened. This appears to affect other wave files in the project as well, even if the file was imported after the steps above are followed. Sometimes this only occurs when panning over the top section of the menu: Which includes(play, stop, create cue, create dialogue) but not the rest.
-Also occurs in QA Game
Expected: Sound Wave Action menu does not close out unless user intentionally exits it
Results: Sound Wave Action menu automatically closes out when user mouses over other options
