Dear TGNelson99119,
Good day! Thank you for posting to Microsoft Community. We are happy to help you.
As per your description, please don’t worry, we can work together to narrow down and resolve the situation.
Based on my test result, with your data set in Excel 365 app, I can confirm I also meet the same behaviour(repro)as like you described above.
Since I also got the same result as like yours in Excel. and the zip codes not displaying on map chart The possible reason of this issue is related to the back-end, we suggest your contact IT admin of your organization and raise a ticket in Office 365 admin center-> Support-> New Service Request. Please don’t mind that we couldn’t provide further assistance because need to check from back-end side and we appreciate your efforts in this case. The support team will involve more resources to check from the back end and provide further help.
Your understanding and patience will be highly appreciated. I hope that you are keeping safe and well!
Sincerely,
Waqas Muhammad
