Content Button Bundle - "Marker ●"

If there are only the three files mentioned, you should not get the dot button.

  • dot → you can shift+click on it for either a config or an alternative family to load
  • wihtout dot → you should not see the dot

so this is an issue in the pyRevit code base
I tested it, and I see the same thing as you do.
