PMDG B 737 800 Winglet pink passengers MSFS 2020

[hotas]

Again, and again after hours of testing the seated passengers only work with the house livery (winglet)of PMDG .
I installed a same livery via the ptp file in the OC , tested and passengers sits down and they all look like pink zombies.
I am really not amused with this. I have run again the FSDT installer, checkbox passengers on /of as mentioned in the manuaL.
I hope really  someone can give a solution. FSDT where are you?
Thanks in advance for any help

I can confirm that seated passengers only work with the PMDG home aircraft B 737 800 SW ,but not with liveries or repaints installed bij PMDG operation center, due to the ptp files ? as mentioned,in the GSX manual.Is there a workaround possible?

This seems to happen if the author of the .PTP file made it with Seated passengers already enabled.

Any way to correct this?
