Font Libraries can easily be renamed with any custom text. I have accidentally changed the name myself when selecting the library’s name but you can easily re-edit it back. Just click the library’s name and the text should become editable.
On a side note, I noticed you are connected to the WebINK font library. I wanted to share that Extensis’ contract with WebINK font vendors expired at the end of June 2015. That means all new updates of Suitcase Fusion (from version 17.1.0 and on) will remove access to these fonts.
We are looking to offer alternative font libraries in the future but WebINK unfortunately is no longer.
I apologize for the inconvenience.
