When using Quickstart Buttons, sometimes I first hovered over a field that has a tooltip description and then over one that hasn't one. The consequence is that the description of the first field is shown for the second one. To verify this behavior, edit a button's link, hover over the additional properties field and then over the namespace field. Maybe it's better to give all fields a description, even if it's an empty one.
