Had same issue. Found out that if you increase the number of points in MapHelper#createHole, the issue goes away. I set it to 100:

        int points = 100; // number of corners of inscribed polygon

        double radiusLatitude = Math.toDegrees(radius / (float) EARTH_RADIUS);
        double radiusLongitude = radiusLatitude / Math.cos(Math.toRadians(center.latitude));

        List<LatLng> result = new ArrayList<>(points);

        double anglePerCircleRegion = 2 * Math.PI / points;

        for (int i = 0; i < points; i++) {
            double theta = i * anglePerCircleRegion;
            double latitude = center.latitude + (radiusLatitude * Math.sin(theta));
            double longitude = center.longitude + (radiusLongitude * Math.cos(theta));

            result.add(new LatLng(latitude, longitude));
        }

        return result;
    }```
