Award Data Incorrect

Award data for BA appears incorrect, at least for some routes. Eg check LHR → BUD for say 8th Sept, app shows 4 flights with lots of availability in business and econ on all flights. Check ba award booking and there’s only 3 physical flights listed that day not 4 and no avail in business on most. Seems consistent with other days as well. Has been like this for over a week.
