I did the same thing a few days ago -- I booked 3 segments in Business on KE via Delta miles. I'm scheduled to fly SFO-(DL)-LAX-(KE)-ICN-(KE)-SGN // SGN-(VN)-ICN-(KE)-SFO. When I hit Select Seats at the top right, it shows seat maps for all flights except the VN one, however the site errors out trying to select seats on the KE flights.
I called up KE, selected my seats, and then when I went back to my Delta PNR and looked at the seat map for the flight, lo and behold the text was still "Not Selected" however the seats I had picked were X'd off the seat map.
TL;DR If you're worried, call in and re-confirm. I just think they're not annotating the Delta PNR, but their own, and not syncing them up.
