The hud is working fine, but I'm wondering if I can get rid of the letters 'pr' in front of the preflop raise. It takes up space. I want the number for preflop raise, but I don't need those letters in front of it. Can I get rid of the letters and keep the number?

Absolutely.

Click Configure --> Configure HUD, choose the profile (tournaments or cash) you want to edit from the drop down at the top left. Choose the Player Stats group on the Groups tab and go to the Statistics tab. Click on the stat you want to edit at the top right, and in the Statistics Properties section, remove the prefix listed there. After you've removed all of the prefixes you want, click OK and you'll be all set.

You might want to take a look at the HUD FAQ which goes into some of the myriad ways in which you can edit your HUD.
