This flight was originally scheduled to be a type X aircraft; but was downgraded to a type Y aircraft. One of the Customer Service Reps asked me if they could use the blocked seats; X5 and X6 because first was booked with too many people and they would have to downgrade two passengers. I said no; X5 is my assigned jumpseat due to the FAA exemption guide due to COVID. My normal jumpseat is X5 inboard; but the exemption reference guide has my assigned jumpseat as seat X12 for this aircraft. There were three agents working the flight. Boarding was chaotic as they were trying to depart to as close on time (the aircraft swap made the flight late) as possible. The door was closed quickly and there were two passengers sitting in seats X5 and X6. I asked them if they were assigned those seats; because when I looked 20 minutes prior they were still blocked in my link. They had boarding passes that gave them those seats; so I had to sit in my normal jumpseat of X12 inboard. I was specifically asked about it and I said no; so I'm not sure why two passengers were placed in those seats and how those seats were able to be unblocked in the first place.
Flight Attendant reported being displaced from the seats assigned due to COVID-19 changes; by passengers assigned to the seats.
