Cannot add or delete items to library
Since upgrading to the latest version of InDesign I am no longer able to add items to a library. It wants me to migrate my libraries to Creative Cloud, but I would prefer these files live in the same Dropbox folder on my computer in which my .indd project files reside.
I use this feature heavily for icons and symbols used in my publication and I'd like to find a solution for this.

As you can see above, the add item and delete item icons are greyed out. Please and thank you.
