Xerox GPD Generic Preference showing instead of Xerox Preferences

Hi!

Within our organisation we are using around 200 Xerox 3655's and 7830's but we are facing many problems with the Xerox GPD drivers.

Since we start using Xerox GPD V5.585.130 PCL6 our users are experiencing the follwing; The print job reached the printer, but subsequently nothing happens and the job disappears.

In that case on the client side the Generic Prefences are being showed instead of the Xerox Prefences;

Also the driver properties are not being showed correctly;

Restarting the spooler fixes it for a while but the problem is randomly comming back.

We tried;

-Updating the GPD to version: V5.617.7.0 PCL6

-Cleaning the spooler on file and registerlevel on the printserver and clients

-Reinstall some machines as a test, this machines also facing this problem

The OS we are using;

-Windows 10 1607 and 1709

-Windos Server 2008 R2

Secure print software;

-Ysoft versie 5 MU25, C.0.25.004

I'm pulling my hair out over this issue, i'm out of options, please help!
