Extension Price on Report not calculation discount %

Running standard report in Sage 100 and the report is not calculating the % that is put in  the discount column of the order.

example:

qty 1       list price     100        discount    10%      extension   90.00

 

the report will read qty 1 list 100  but then it will say the extension is 100. it is like it does not take into account the fact there is a discount column

 

any way to fix this on a standard sage report?
