I have a descision step in my workflow. The paths are "Change" and "Continue" (screenshot wf1). The path is determined by the task result.

But this is not behaving as expected. If I action "Change" both paths are followed (screenshot wf3) - I don't want that, I only want it to follow the "Change" path... If I choose "Continue" it follows the "Continue" path but then also has a fragment of the "Change" path taken (screenshot wf2). Any ideas what I'm doign wrong here?
