Positive/Negative Rules No Ability to Access

Hi All,

I do not have the ability to change the positive/negative rules in the membership plugin via the "access levels" configuration area. I looked at p.37 of the membership how-to guide, and my screen is missing the ability to drop in the specific rules (see my screenshot attached). The check boxes and add/remove, update sequence does not work either.

Please help! Thanks, Amber
