When you say that you "deleted" the entries, do you mean that you actually hit the "delete" key to blank them out? If so, instead go back and enter 0 (zero) for each field, and see if that improves the situation.
Otherwise, you should be able to "remove" the form by going to Forms mode (top) and viewing Schedule I (this is where these numbers appear), then at the bottom of the screen, press the "Delete Form" button.
Then go back to Step-by-Step mode and see if the fields are now blank.
