Category Collection - Category items not showing up on right pane

Hi, I created a category collection within a folder that contains all the information regarding a project. I also have a master Category Folder where I want to keep all the categories in it. The idea is that the category collection will only have categories that are relevant to the project. Whereas the master category collection will have all the categories. I create a new category topic in the master folder and then drag-n-drop to the project collection.

The problem that I'm having is that when I want to tag a reference and I select from the pull-down menu the project collection it is empty. It does not have the category topic that I drag-n-drop into the collection.

Any ideas why this is happening?

Thank you,

Julian, The current release

Julian, The current release only allows categories folder to be displayed in the right panel. Collection and Smart Collection will not work. This may change in the future.
