I have tested the provided demo with the R1 2015 version. It appears to me that it works as expected.
If an update has to be initiated, it would be best if you upgrade to the latest version. At the time being, the latest version is 2019.1.220.
With every version new features are introduced, a lot of enhancements and bug fixes.
Let me know in case you encounter any issues with installing the latest version or with implementing the suggested functionality.
