Tax rate not updating

Hello Altruists,
Noob Magento ( 2.4.3-p1) )user here. I am following the mazeplaza guide (https://www.mageplaza.com/kb/how-to-import-export-tax-rates-magento-2.html), and the csv file uploads ok, but the rates are not updated. Using OpenOffice calc instead of excel btw.
I have arranged and renamed the columns as suggested in the link, and following this format:

Manual rule update works, sample file from github works, but my files does not -_-. Please advise.
