Hate to ask, but are you sure? This is the same type of road with highway=service key/tag I fixed Wednesday.
It shows up for me on cruiser.

And I'm sure I'm looking at the right place in the theme because if I change the outline to blue I get this:
Anhang anzeigen 1439045
Line 234 in the theme file. It is also the only spot in the theme that matches the road conditions.
Can you maybe check that line with the theme on the device? It should read:
<line cat="roam2" stroke="#000000" width="1.5"/>
Where the 1.5 was wrong before (1.0).
