Find and recode

I am trying to bulk find and re-code . I tick all the boxs re-code to sales and there are 2 things
there is no tax option
and it does not seem to re code
I have just down loaded the latest up date and it still does not work

Wait I just did it for the 3rd time and it did but would be nice to have a tax option as a couple of clients have started gst part way through the year I could find and re code all sales from a certain date including gst
