The "collections" in this area were originally filters in MM3. The empty items don't correspond to any of those filters; all the original filters are accounted for. If selected, the empty items are not deletable.
The selected item, which is barely readable, is not blank; the problem there is that the text color being used is the wrong text color. Presumably, this color is used because some items have a "disabled" color (meaning what? who knows?) and the owner-draw logic only supports the difference between enabled and disabled, with no attention given to the selected/unselected state.
It would be nice if the checkboxes were shown using the default, not-disabled color, but that's an issue with in-listbox controls all thru the options.
