Moving items in a list up/down

In an earlier version of miracheck cloud I was able to use arrows at the top to reposition new items either up or down within a list. This method has been deleted and it appears the triangle up/down arrows are to be used to reposition an item. Clicking on these arrows is a FAIL and I would like to know what I am doing wrong as this new and improved method is wasting a lot of my time.
