Hi Frank22
If you're updating the prices of items already existing in the data file which had Sell Price Inclusive ticked, it would remain ticked even if the Excel document has nothing in that field ( No character in the Sell price inclusive indicates that the prices are not tax inclusive) .
It works only if the item to be imported is new or for items that never had Sell Price inclusive ticked before.
In the meantime, can you please try entering N in the Sell price inclusive for those items and do the import again and check if its unchecked?
