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:

Start by reproducing the Java request shown in the issue, using MapboxMapMatching.builder with PROFILE_WALKING, the supplied coordinates, and the stated options. Compare its matching and steps with the Directions demo, then trace whether the discrepancy is exposed by the Java API or occurs in the underlying service. Done means a confirmed cause and a documented actionable resolution.
