How to delete Profile Sets

Hello all

I have created a vertical profile to design my vertical alignment.

Over several days I created many different vertical profiles thinking that if I deleted the old profile then all information for the profile would be deleted.

However I have noticed that all of the previous vertical profiles I have created are saved and when I annotate the profile I can see all of the old Profiles under the Profile set arrow.

How can I delete all of the profiles?

Below is a picture showing all the different profiles in the drop down menu.
