[D&D 3.5] Ability Mod issue?

Hey all, I'm relatively new to the site and I've looked in a few places and couldn't find anything that could answer my question properly. I'm working on a journal entered Character sheet and I've come across an issue. I'll enter my Dexterity Modifier in the Base Column as 18, and the Total will change to 18, but I'll get no ability mod and it doesn't add my dexterity modifier to my AC. HOWEVER, it does automatically update my Initiative to 4. Can anyone explain why this is, or how to fix it? Or should I just not use the AC section on the token and input it manually?

Just a guess.  Is Dex Bonus unchecked by chance?

If the dex bonus is checked under the AC Ability Bonuses, you can also try going into the Misc tab and hitting the checkbox next to Ability score recalc to force the sheet to recalc the bonuses for you.  If you are seeing NaN in any of the ability score fields, delete the existing zeros and then put a zero back in that column to force the system to recognize the zero.

I took some screenshots, if you all would like to see, but the Wisdom modifier seems to have appeared in the Ability modifier column, but no other stat mod has been made. Dex bonus **is** checked (Though under AC Bonus and Capped AC Bonus it shows a 0), I have checked the box next to the recalc, and I am not seeing NaN. This is happening the same way on **both** of my players' character sheets (though the mod that appears on one sheet is Cha whereas the other sheet is Wis). I do **not** have screenshots of the second character sheet, though I have no issues taking them. The Screenshots **are** fullscreen Screenshots using the Print Screen key, I apologize if this is an inconvenience.

Hmm.  Yes, please post the screen shots. 

Hmm... it seems that closing the game window and reopening it seems to have fixed the problem. Thank you all for your help!

I'm glad it is working for you.  Let us know if you have further questions. Happy Gaming.
