culpdesign on "[Plugin: WP-Filebase Download Manager] Turn off +Add Category in Category fly-out when adding files"

How do I turn off +Add Category in Category fly-out when adding files?

I have a lot of categories, and my menu has doubled with a +Add Category under every single entry. Not only is it very long now, but it is hard to read and I can't find where to turn that off

Thanks
