Configure XRDP / XSESSION: Remote Connect to KDE

Evening, having trouble connection from my Leap KDE to a remote Leap KDE. Need a guide on how to configure the xrdp / xsession to successfully and consistently login into my other Leap KDE OS.

Debian KDE 1) I can successfully login with the default configuration:

Leap KDE 2) I made no changes but I get this:

and can not login with this and has a different login dialog appearence:

Thanks!..
