Seat Ali/SharanMemory Seats wrongly programmed by factory

Hello Together, after almost 10 years in the possession of a Seat Alhambra I noticed the following: Seat adjustment via position button (without ignition) can only be adjusted with button hold. So it was always (annoying me also 10J) Now I noticed that when the ignition is on, at a single pressure on the button Pos. 1 or 2 the seat immediately drives into the correct position. Unfortunately he does this during the ride too. Does it actually belong to something else (safety aspect)? Can the order be changed via VCDS? So touch function when boarding (without ignition do not make the ignition first) and touch stop function when ignition is on / driving. Or is it something else?
