I tried every combination and finnaly found the issue - BUG, LIMTATION
Attribute Names can't have quote signs, as it screwed up the javascript for ajax. I had an attribute caled "Women's Size" - notice the single quote. Renaming it to "Women - Size" fixed the issue. I guess one would not allow quotes in attribute name admin validator...
Maye it would be wise to verify other instances of this applying to other fields.
Any ideas to address this? Validator or something else?
