I have deleted quite a few templates, that are gone for a little while then like ghosts, reappear without warning. Where does MT4 store this info (other than the templates folder) and how do I kill them off completely?

I have deleted them using the delete function, I have manually deleted them from the folder and have re-installed MT4, but they will not die. Also old profiles - same thing. Please ... how do I make them go away?
