Seaside dinning hours in MDR

What are the dinning hours for the 1st and 2nd sitting in the MDR?

Last week it was Seashore at 6 and 8:30. Ipanema at 5:30, 7:45 and 9:45. Marketplace at 6 and 8:30, but my understanding is that Seashore was going to be changed to include 3 seatings and that Marketplace was going to be buffet only starting this week.
