I'm saving some outlines from the web which are PDFs. Once I save them in Word and apply a auto numbered outline, I get the following results.

1. 1. Marveled (v. 13a).
2. 2. Realized that Peter and John had been with Jesus (v. 13b).
3. 3. Admitted that a miracle had been performed (vv. 14-16).
4. 4. Threatened Peter and John (vv. 17-22).
a) a. Commanded them not to speak in the name of Jesus (vv. 17-18).
b) b. Peter and John said they could not but speak...(vv. 19-20).
c) c. Let them go after more threats (vv. 21-22).

How can I remove the first three characters after the auto numbering and get the results below?
