Hi I'm not quite sure what you mean. Could you send me a screenshot of your layers that you're having trouble viewing? My categories are all showing up!

If you select a layer, the items categorized in that layer will show up. If you wish to deselect your layer selection, you just need to select "all" at the top of the layer tab to view everything again.

I believe your questions have been answered so I'm going to go ahead and lock this up!
