Swiss seatmap differences.

similar to what Sabbasolo reported above, I see more available seats for Swiss (LX) on EF than directly on Swiss.com
For example, I see 8 free seats in Business on EF, but only 4 on Swiss.com.
This is not about blocked seats. - Those I can understand.
The seats which I book are correctly updated on EF, so it's not entirely out of sync, and I'm looking at the correct flights, but EF just shows seats as open which do not appear as bookable on Swiss.com.

Example: LX1050/12Sep ZRH-HAM.

EF shows seats 1F, 3ACD as available (plus many others)
Swiss.com shows those 4 seats as occupied.
