Hi @amysondavie - Thanks for reaching out to us here on the Square Seller Community.
Did you happen to save the original file you exported from your library before you made any changes? If so, you can import this back into your Library to restore your items. Otherwise, your Library will reflect your most recently imported file.
I hope this information is helpful but please do let us know if you have any additional questions. Always happy to help! 😊
