Error in ‘Add New Image/Objects’ in Catalog Plug-in

Hey there,
I just installed the Catalog Plugin and after clicking the "add new image/objects", I received an error pop up message that says, "[object Object]".
When I click "Ok", the status bar below says, "NaN%" and no object/catalog item is created.
What do I need to do to get rid of this?
Thank you for your reply.
