errrr.... jp's, the joint parameters. if you've never messed with them, check out clint's tutorial, over on the character creators forum. the joint editor doesnt have the rotation stuff??? i've never seen that happen :/ the bend parameters disappear when you turn on 'curve' for a part, but the twist never disappears. if you have ik turned on, try turning it off and see if they appear. other than that, all i can do is give you my quickie, five minute jp explanation: bend X: everything between the green arms DOES move. everything between the red arms does NOT. between the red and green arms is the blend zone. twist bar: everything past the green end DOES move. every thing past the red end does NOT. between the ends is the blend zone. mat spheres: everything inside the green sphere DOES move. everything outside the red sphere does NOT, unless it is also in the green sphere. between red and green is the blend zone.
