This problem is also sending my mental! I changed the order to Album and Date....then it starts to sync all over again...but its as iff "Facebook Wins"....the annoying thing was, I had other albumbs correctly ordered and Aperture changed them, now I cant change them back. Its like Aperture wants manual setting only...or anohter setting...wasted hours of my life....again....
It takes so much time to sync "order"...you may as well have uploaded the entire album all over again. This is the 3rd time I've tried. Its also chaning the share settings...grrrr...
It just worked...but it took a few times. I also found what the "friend seeting problem was...go into apps in account settings on your facebook and change the settings for default.
