On my facebook profile under the activities heading it reads "Wenkel Rotary Engine." When I go to edit this out of my profile I click on the little 'x' opposite of the 'interest' that I want to get rid of, it asks me if I am sure that I want to do that and I say yes, so it's gone, except not. One the page appears to have been deleted it does not allow me to save the changes to my profile because it is almost like it is not registering that anything has been changed, so I moved one of the interest around, and then it registered the change, but when I go back to my profile it is still there. I tested to see what would happen if I added a different activity to the heading and it proceeded to allow me to delete it and on my profile page it was gone, but the "Wenkel Rotary Engine" page was still there. What is going on? HELP PLEASE
