WALKING MapMatching issue

We are working on a app that uses the mapmatching api. We seem to have some problems when it comes to walking matchings/steps. Many of the roads dont seem to be included when matching with this profile. Is there any way that I can add these roads to the walking profile so it matches the points correctly like in the example Directions demo?

This behaviour only seems to be an issue when using the WALKING profile.

Some additional info:

    Point point1 = Point.fromLngLat(6.525440, 52.115350);
    Point point2 = Point.fromLngLat(6.526132, 52.115345);

    waypoints.add(point1);
    waypoints.add(point2);
    
    Locale locale = new Locale("nl_NL");
    Arrays.fill(radiuses, 50.0);
    
    MapboxMapMatching client = MapboxMapMatching.builder()
            .accessToken(Objects.requireNonNull(Mapbox.getAccessToken()))
            .geometries(DirectionsCriteria.GEOMETRY_POLYLINE)
            .profile(DirectionsCriteria.PROFILE_WALKING)
            .overview(DirectionsCriteria.OVERVIEW_FULL)
            .coordinates(waypoints)
            .language(locale)
            .steps(true)
            .roundaboutExits(true)
            .bannerInstructions(true)
            .tidy(false)
            .radiuses(radiuses)
            .build();

Result:

Expected result:

まず、Issue に示されている Java リクエストを、PROFILE_WALKING を指定した MapboxMapMatching.builder、提供された座標、記載されたオプションを使って再現します。そのマッチングとステップを Directions デモと比較し、次に、その差異が Java API によって露呈するのか、基盤となるサービスで発生するのかを追跡します。原因が確認され、実行可能な解決策が文書化されれば完了です。
