Everytime that I try to import a spreadsheet that is in Compatibility Mode, the first column is missing.
Once I open the file, habilitate to edit and save it again, the column reapear on the query. I guess that some error is happening in this context on M.
As this source comes from a website that refresh the data daily, is a big headache to do this procedure manually, knowing that all can be easilly coded.
thanks
