Hi, I've been trying to process this file but whenever I do I get the following error message: "Not all of your data could be properly processed. Please review the error below and upload a new file. ERROR: Could not load the spreadsheet data."
I'm not sure if it's because there is a problem with the reference spaces. I'm not sure if the system is detecting properly all 19 municipalities even though a shapefile of this has been uploaded previously.

I'm including the attachment that I'm using to process the data.
