Layout PDF

Hi,
i recently switched from Rhino 7 to Rhino 8 and have a problem with exporting Layout as PDF. I created a custom display mode and in the programm itself everything looks as it schould be, but when i’m going to print window it looks different, specifically objects under other objects are not visible, even tho in the settings it is set to be the other way. Underlaying objects become visible by printing only if i switch to raster output, but i need it to be vector. In Rhino7 with the same settings everything worked the way it schould. Does anyone know how to deal with this problem?
