Excel Error Message Help

Copper Contributor

Please see the error warning image below. I have a massive spreadsheet that I've built from scratch originally in Microsoft 2011 Excel version 14.7.7. Despite starting from a blank template, I have run into an error message I do not understand. 

 

The message pops up every time I copy an existing worksheet to a new one within the same workbook. It appears 11 times, each time the name (in the attached image 'Concepting_Prototypes') is a different name, and they are unrelated to the content of my workbook. If I click "Yes" 11 times, the messages go away. If I click "No," I have to rename whatever detail this is referencing, and then it adds that name to the list of errors (so the next time, I have 12).

 

Where is this issue located within my document, and how can I remove these details to prevent this error? As I mentioned, it does not reference a detail relevant to my workbook content, and it is not something that appears on the worksheet.

 

Thank you in advance!
