how can I make GST and taxtotal on the receipt with towa ax-100?

Hello, thank you again for helping me out last time - that logo & commercial message question. I have to reset everything on the cash register after initializing it. On the old receipt, there is two sections on which respresent 'GST' and 'Taxtoal'. I set up the tax rate as 10% and it should be printed on the receipt according to the setting from flag 5 - #6 and #3, however, there is nothing to show up. I think that I did make somehting wrong and can anyone give me a hand, thank you.
