I had some trouble during the refraction/reflection process, as well as for the second to last part. I tried changing around the settings and redoing my steps but I didn't have much luck fixing the issue.

I also experienced that my render result looked similar to yours after adding a directional light. As I remember, the directional light’s default was 100, and I just tried changing the default to 1, then the results were okay. I am not sure that your case and my case are the same, but I hope it will help you to fix the issue.
