Looks like you added the ability to share slicing profiles, which is great by the way!
When that featured showed up, I think that all of my student’s profiles were added to my list, so now I have ~25 slicing profiles for the printrbot simple metal, many of which are duplicates. I can go through and delete each one, one by one on the My Slicing Profiles page. But when I reload the page, all of the deleted profiles reappear. Any restrictions on what I should be able to delete?
