OK - in the event there is an issue. Just MY advice, does not make it gospel....
CALL CALL CALL CALL. Until you do, you really will not know if this is yet another Disney Website Issue, or if there is really no place to eat.
In the event that Disney does not want to let you eat.... start looking at the myriad of non-Disney owned restaurants. Dolphin - Swan - DTD.... there are a number of these, that may be contacted DIRECTLY.
