Does the system interpret that combination (business + upgrade) of preferences as a request to upgrade to first?
Does the system display only upgradable fares whenever any upgrade is requested?
Apart for some other, possible but illogical combinations of preferences, I'm not certain I understand the process of requesting upgrades online.

To buy a ticket that is upgradeable from economy class to business, select "economy class (lowest)", then select "upgrade using systemwide region 2".
If you select business and then also the region 2 systemwide upgrade, you are trying to buy a business class ticket that is upgradeable to first class.
If there are fares available, they'll be displayed. You can tell since there will be an "upgradeable fare" notation on the right side of each flight leg, looks like a pencil or a carrot next to it too.
If that notation isn't there, you'll probably see bold lettering toward the top middle telling you that you have selected a valid upgrade but that there are no fares available. Hope this helps, it's really not that hard.
