Thank you for your hint! This is probably the problem. In my styles I

# motorways
highway=motorway {add oneway = yes; add bicycle = no; add foot = no; name '${ref|highway-symbol:hbox} ${name}' | '${ref|highway-symbol:hbox}' | '${name}'} [0x01 road_class=4 road_speed=7 resolution 12]

highway=motorway_link {add bicycle = no; add foot = no} [0x01 road_class=4 road_speed=4 resolution 16]

I re-used a fileset from the All-In-One server.
