Estimated Passenger Number Unchecked does not do (You will be prompted etc.)

[CVJ]

I was trying to eliminate the glacial slow boarding of passengers and crew by unchecking the the Estimated Passenger Number in Settings, but even though I saved the change, the passengers keep marching in one by one.

This is in Sea-Tac (KSEA) at Gate D4. Aircraft is the PMDG 737-7.

Would appreciate anyone helping me fix this. Thank you in advance.

(Happy to report that the "Follow Me" vehicle guided me perfectly to the gate  ).

Change the density.   Settings>Timings>Passengers Density.
page 29 of the Manual

I have done that (Changed the Passenger Density to "Sparse").

Made no difference...

Still need Help - preferably not from a newbie like me

That's the opposite of what you are supposed to do. To speed up boarding/deboarding, you need to raise the density.
