I think sp usually tells the show the week of maha epi that they need to make a longer episode for the week and then the ph has to scramble to create a ME worth track hence this weeks ffwd of days so the big ivf kaand can happen. Other shows just drag the main point to the next week anyway. Look at last ME they dragged it and till monday we didnt know how the stupid engagement ended lol only the segments gave us a clue lol
