Clearing out 'planned training'

I started a BT training plan a couple of months ago which I didn't follow through with. Now I want to clear that training plan out of my 'planned training' area on my log so i can put in new training plans. I have already gone in the control panel and deleted the plan, but when I look at my log, there is still that planned training on the left hand side that has stuff in it. Is there a way to get rid of all this?
