Invoice Discounts Broken

There are numerous problems with Discounts.

A) the Discounts column cannot be removed.
B) one row of Discounts is in %, the next row of Discounts is in $.

Overall I need to have Discounts column removed because it makes the invoice look "cheap" when you don't offer an invoice. Is there a way to remove the Discount column because I can't use it as is.

go to Settings --> Localisation. All the way at the bottom is "discount locatin", set jt to "disabled". The discount column & the "discounts" line with the subtotal & taxes will be removed
