I don't know which effects you have with your clip, but you can readily delete the unwanted clip by placing the cursor over it, left click (it should get a red enclosing marker) and then use the "delete" key to delete it. You should then be free to insert your new clip into the space on the timeline, it can be expanded to fill the empty space by clicking the cursor on the edge and dragging to the desired width.
