Routing is only in resolution 24. If you put that information into other resolution it is ignored.

Hi

Not an answer to your question, but maybe relevant:

The default style has, in "options":
levels = 0:24, 1:22, 2:20, 3:18

My reading of the "Style Conversion Manual" says that elements with
a resolution between the levels are included in the higher res/lower
level map; ie. elements with [resolution xx-23] go into the level 0
map.

So, according to this, you will be getting 2 lines on top of each other
at the most detailed level.

If this isn't the case, the manual should be clarified.
