Dear Maintainer,

*** Reporter, please consider answering these questions, where appropriate ***

   * What led up to the situation?
it's been bugging me for a long time

   * What exactly did you do (or not do) that was effective (or ineffective)?
sometime when I click to expand a folder in list of folders, Dolphin also expands another folder that 
I had recently un-expanded,

Dolphin should only expand the folder whose twisty I click.
