Wayne, the hole table follows your calloutformat.txt file (same as the hole callout tool), so the first thing I would test is whether a regular hole callout on the feature looks right on any tapped hole.
If it does, then consider this: the hole callout can be thrown off if you add a cylindrical cut to make a counterbore or countersink on a tapped hole. sometimes this is neccesary, in which case, you'll need to fill in your hole table manually with the values that you want to show up. If possible, use the counterbore settings in the hole wizard.
