change capacity for roadvehicle

[sky81]

Hello ,

I want to change some parameters for road vehicles inside eGRVTS2.grf, I I did for some of them. But when trying to change the capacity of a road vehicle I cound not succeed. Can someone help me, please?
For example: 1 Horse Small Passenger Carriage has 6 passanger as a capacity.
If I look on action0, Property 0F is all the time 00, meaning?
But there is a action 02 look like this:
10875 * 23 02 01 BC 89 10 00 FF 00 00 00 01 06 80 0F 00 00 00 0F 00 00 00 FC 00
I saw for other vehicles that 06 above is changing to 0A for the one with 10 passengers. But when I change it, nothing happens. Can someone help me?

Here is the NFO decoded for these road vehicle:
