Hidden Lines are missing in vector output from Layout

Topic basically says all. I am trying to do plans with vector output. In addition to a previous issue (Fillets look weird in PDF vector output I am now experiencing hidden lines disappearing when I’m printing to pdf from Layouts. In raster output everything is there, when I choose vector, no longer so. Please see pictures below for details
