I'm not sure what might cause this issue since I haven't had it myself. If you haven't installed UO using the ML link that can be found on this site try that. You also can't be running any other macros simultaneously that have targeting in them. Try once manually using your pickaxe on a cavern tile under you and then running the macro. Let me know if any of these things did/didn't work for you.
