Problem with route_master

The California Zephyr is a passenger train in the United States. The westbound train is Amtrak number 5 (ref:5) and the eastbound train is Amtrak number 6 (ref:6).

Since the reference number is not the same for both the eastbound and westbound route, I tried using a semicolon for the route master ref (ref:5;6)

However, Osmose flags this an an error since ref:5;6 does not match either route relation ref:5 or ref:6.

Any ideas on how to solve this “error”?

Amtrak number 5 relation:

Amtrak number 6 relation:

Route master:

If you are sure it’s not an error just tell osmose it’s a false positive.
