Course Presentation

Shapes: cannot get 100% width

I'm trying to create a "header" region in my course presentation content by creating a rectangle shape with a white background.

When I resize shape and attempt to make it stetch the whole width of the presentation canvas, I am still left with a gap on the right-side of the shape:

When I inspect the shape element, I can see that container has a max width of 99.7821%:

Using the course presentation type with Word Press

I am trying to generate a course presentation type in WordPress

1. Having failed to create one on a site with a security certificate, I moved to an insecure site.

2. On my test site I can create the object but no slides and can see the following error messages in Chrome:
