Hi Bill,
I just checked my layout in Therion 5.3.16
layout AB
scale 1 1000
debug station-names
symbol-colour area water [0 0 70]
symbol-set AUT
color map-bg 90
#debug on
symbol-show group centerline
endlayout
layout BB
scale 1 1000
endlayout
export map -o ./export/ab_plan_1_171114_AB.pdf -layout AB
export map -o ./export/ab_plan_1_171114_BB.pdf -layout BB
