Cannot add multiple scene types within the same project

I need help with the following issue. I have created a project with scenes that use image tracking, and I would like to create a scene with global tracking. When I select ‘Create Scene’ with the new tracking type the website becomes unresponsive. Has anyone encountered a similar issue ?
This is very frustrating since it means that I am limited to one type of tracking for projects. The video tutorial published by Zapworks clearly states that multiple tracking types are supported:


Any help or support would be greatly appreciated.
