My character sheet don't add my Dex mod to AC after it broke, after trying to fix it configuration on sheet it still doesn't work. Please help

I am playing pathfinder and I am using Pathfinder by roll20 character sheet (1e), I used buffs to have add bonus to my ac and dex mod (cat's grace and mage armor) but then it stoped working, I could not change temp in dex (but I fixed it now) and my AC don't look at my dex mod, @{ac_ability_mod} is stuck on 3 while I have 5 dex mod. I tried changing it in configuration on sheet but it didn't work. Now I am looking at "elements" after I opened console Please help, 

Okey update, it doesn't calculate ac At all trying to change from dex to int/ con also don't work

Okey, Problem seem in total weight.... When I cross light load my character could not get more than +3 bonus to ac....

Yeah, medium load effects your max dex bonus applied to AC and dex based skill checks. <a href="http://www.d20pfsrd.com/gamemastering/exploration-movement#TOC-Carrying-Capacity" rel="nofollow">http://www.d20pfsrd.com/gamemastering/exploration-movement#TOC-Carrying-Capacity</a>
