Hey,
currently, you cannot configure more than one osm file for the ors.
Thus, I’d assume that the second entry overwrites the first, and you only get german data.
To check whether you’re running on the “default” data or on your germany-data, request a route anywhere that is not near Heidelberg, e.g. Berlin or Munich - if it works, you’re not running the “default” data.
(Also, building should take more than minutes if your pbf file is decent-sized).
To use data from germany and the netherlands, use a tool like osmium or osmosis to merge the two pbf files into one, see this comment.
Best regards
