Justin,
Each axis type has a range of 'expected' (= shown) frequencies, which you can set in the 'axes' dialog (in the Windows menu). There you can change the minimum and maximum freq. for 15N (also needed to see any charged 15N sites, for instance). This setting seems to limit anything you set for the min and max aliased frequencies, as you seem to encounter.
