Wherever WOAI aircraft plans are you wont see FSX default AI. It is an issue with the new way FSX AI plans are done. It will take a little time till the plan structure is sorted then the old FS9 plans convereted to FSX structure. Its still early days, just be patient. The only way to get all the default AI back is to remove WOAI. PAI planes will do the same.
