I travel the USA extensively and use WAZE all the time. Every once in awhile I have to clear out the Navigate and Favorites lists. It takes 5 taps for each deletion and can take a long time to clear the lists as each entry has to be done separately. I suggest an "Edit" button, bringing you to either list, with a box next to each entry. Tap each box related to the location you want to delete, and once you have tapped (checkmark) all you want to delete, then tap a Delete button. Also, a Delete All button.
