Hi, I wrote to the regular GCU Support about this, but you may be able to fix this faster.  I've been updating my Artist's Notes and when I went to make changes to my Purim Party Invitation, Product id: 894413, a box popped up that said I must first delete a duplicate category. Originally I had 2 different categories (please see old notes) and had requested a category for Invitation>>Party>>Purim as there was none a year ago.  
 
Someone added a second category (not me) and it is a duplicate. This glitch is keeping my edits from being saved as I cannot progress until that duplicate category is removed. if Party>>Purim is now an official category, please add that for me as I cannot make any changes as it is.
Thanks!
