It sounds like the Excel workbook you’re working with has retained links to a previous Workbook you created – you can confirm by going to the ‘Data’ ribbon and clicking ‘Edit Links’. This means that certain inputs on the new Workbook are being pulled from the previous Workbook, and the only way to fix this is to manually edit the inputs where those links were created.

To identify if a link was created, mouse into cells in the new Workbook and in the formula bar look for the name of the previous Workbook in that formula. You would then need to edit the new Workbook to remove every one of those links, such that they link to the information within the new Workbook. Depending on how many links there are, this could take a lot of time. It may be more appropriate to just return to the previous Workbook and copy the data over to a fresh copy of the All-in-One model.
Spencer has created a Best Practices in Real Estate Financial Modeling Guide that addresses these sorts of cross-Workbook links, and how to avoid them when copying from one Workbook to another.
