I'm thinking this is how your Styles are set up. There are about 40 odd settings for all of the different hole/thread/counterbore/etc... combinations the HOLE command can make. You can set them up how you want.
The FIRST example in the diagram in the previous post is the correct method of indicating a counter bored hole ie THREAD DIAMETER & Pitch NUMBER OF THREADS OF A TAPED HOLE or DIAMETER OF A PLAIN HOLE- OVERALL DEPTH OF TAPED/ PLAIN HOLE then the DIAMETER OF THE COUNTER BORE - DEPTH OF COUNTER BORE from the face from which the hole was drilled as this is considered the datum plane/point.
