Everything I have read says that deferred stock update is an EE feature, but the option is showing up in CE on the product advanced inventory control page (both for configurable products and the simple products under them). Changing the setting does not work. It is stuck on "Use Config Settings", which I can't find. It's not in the store config->catlog->inventory options.
This may be causing a problem and I'm try to track down where the stock is not being decreased after a purchase.
Does anyone have any ideas on what could be causing the problems?
