Hi. Sorry for writing in English, but i dont speak french
If the markers from Denmark2000 is shown, it could be because both routes use the same standard coordinates Lat 0,00000 and Long 0,0000.
I was testing on Denmark2000 for some years and made the markers for it.
It is not possible to "move" the route to the correct coordinates. Please try to uninstall Denmark2000 to remove the markers, and see it the correct markers is shown instead.
