Welcome to the forum.
I see that in Dashboard 2.28.2 also. I think there was a fix for something in that area recently so possibly the fix corrected one thing and broke another. Since the developers have not noticed this thread so far the best thing to do is to submit an issue here so it will not get forgotten.
When reporting it export your mini-flow by selecting the nodes and select Export from the menu (or Ctrl+E) and paste it into the report. That makes it easy to test.
[Edit] I realise now that I was running the dashboard version from github master, not 2.28.2 so I have deleted that sentence.
