Marketpress mp_product content attribute not working

I know this was an issue, and Aaron said he was going to fix it for 2.5.9, but I still can not do anything with the mp_product attribute. I do not want it to show, I've tried 0, false, and 0/false but the full content still shows, regardless. Is this still a known issue?

I am up to date, and I upgraded using he WPMU update manager.
