In the latest desktop version:
1. Go to Plugin tab
2. Click the Browse installed plugins to load one... button
3. At the top I have the wow plugin
4. Click the Name column and it sorts the list alphabetically.
5. At the top I have agone plugin
6. I select agone and the card back for wow shows on the right and loads wow if I select choose.
Sounds like the list is sorting but not updating what folder it points to.
This also happens on the iPad.
