Select the favourite you want to delete and then click on the small triangle button at the top-right of your 'Favourite" palette.
Then choose "delete".
Now repeat for every single favourite you want to delete - you can't select more than on at a time.
Finally hope that Graphisoft will improve favourites so that we can add (import/export) and delete individual and selections of multiple favourites as well as grouping them into sub-folders.
