Well, your items should be now grouped in a repeater (or an equivalent type of widget), which is a grid of similarly designed elements used to display elements of some cathegory in your CMS. If you see your items jumbled up there chaotically, that means that the repeater is connected to a dataset, which in turn is a linking structure between your backend and what a user sees.
What you now need to do is to go into its' settings by clicking it with a right mouse button and to turn off the cathegory tabs there. In the picture below it is the second switch ("Show tabs on Service List").
