Set Columns to 2 and click Reset All. Type 96 and 96 into height and width and then click on the right box and then the left box:
While the 1st box is selected change the width to 80 and click the top Apply button directly to the right of it. It should look like this with one box showing 96 and one showing 80.
If this looks correct, click on Send to HW. If the screen looks correct, click the Save button.
