As @mrz implicitly said: the ROS7 recursive routes have different rules than ROS6 for matching values.
In ROS6: “target scope” must be bigger or equal to “scope”: eg “target scope=10” and “scope=10” do match: "target scope >= “scope”
In ROS7: "target scope must be bigger than “scope” to match: eg “target scope=11” needed to match with “scope=10”: “target scope” > “scope”
target scope=10" is a default value.
