strange that I am only seeing one side of the conversation in this thread.

Anyways, the problem is most likely a single dot or object that is left in the original drawing that you can't visibly see. The torch follows the cut path and when finished, goes to that single dot and then cuts it by firing a single hole...then it moves to the next cut path. Soimetimes the extra left over dot is clear in color so it doesn't show up at all but it is still there.
If you have the file and can post it up we can view it to see if that is the actual problem.
