Hi there, @gelkins4!

You don't have to change any settings in your report nor in QuickBooks Online. Instead, you might want to update your MS Office, including your Excel.

If you get the same result, I recommend checking your MS Excel settings. You may check this MS Office article for the detailed discussion or seek some help from an Excel expert.

Let me know how it works. It'll be my pleasure to assist you if you need any other help. Have a great day!
