Swipe Tool only lists catalog layer not individual raster layers

GM 13.1 (b032512) Win XP Pro 32 bit
I have all my raster maps in a catalog. When I use the Swipe Tool it only lists a single entry in the "Select Layer to Swipe" drop down box. There are actually 4 raster layers.
On a related suggestion I have used other software that allows you to right-click a position and select from a list of layers that cover that spot. I suspect the function most likely reads the extents of the maps in the catalog and determines if you are inside or outside the polygons. You can then select the map you want and it brings it to the top of the stack.
Thanks.
