I tried changing them but didn't see any difference. Is there a reprocess button or something I'm missing? When I swapped to velomobile it redrew the route automatically.

Use the following switches to change behaviour

(1=yes, 0=no):

assign consider_elevation 1 # set to 0 to ignore elevation in routing
assign allow_steps 0 # set to 0 to disallow steps
assign allow_ferries 0 # set to 0 to disallow ferries
assign ignore_cycleroutes 1 # set to 1 for better elevation results
assign stick_to_cycleroutes 0 # set to 1 to just follow cycleroutes
assign avoid_unsafe 0 # set to 1 to avoid standard highways
assign turnInstructionMode 1 # 0=none, 1=auto-choose, 2=locus-style, 3=osmand-style
