The positions are sometimes a little bit tricky…if you have two or more at the same place, they are sorted by appearance in the config.js.
You should try to reduce the width and height of the SmartWebDisplay as small as possible.
May be, your widget is in real as wide as red-marked in this screenshot, so you wasted a lot of space. First, you can temporarly change the background-color of the html-file (body bgcolor=#123456) to see the needed space at a glance. Change there the amount of pixels and percentages. Additionally change the height and width in SmartWebDisplay.
If nothing helps, start with your Widget and add one by one your other modules.
