Say I have 2 installed custom properties, prop1 and prop2. If I select prop1 in the top left box, and prop2 in the bottom left box, the uninstall button uninstalls prop2. Perhaps this is not the most intuitive way to do it. A couple of times, I would select the property in the top left box and click on uninstall only to find that I uninstalled some selected property in the bottom left box.
