Delete/Edit Favorites, with latest 13.5

I know how to add or remove favorites but have a strange issue.

Both "downloads" and "articles" are known local or network paths and after the separator line.

The drive F:\ does exist but E:\Temp does not and F:\T-570-Downloads does not

So, easily, I proceed to right click those last and Remove that path but it deleted Articles.
Next I clicked on that last path again, Remove and it deleted Downloads.

Now I was left with E:\Temp and F:\T-570-Downloads and noting happens when I try Remove as I have no more items above that separator line.

How to I remove those 2 last lines ?

Turn off SmartFavorites in Preferences, or remove the item which is adding them to the menu via Customize.
