Screen cuts off when menu collapses automatically

Hi,

I've created a training, in which the first Slide it's the title with a button to Start, I applied to the slide that the menu doesn't show, when the learner pass to the second slide the menu collapses in order for them to view the content.

I would like to keep this configuration, but when the course advances to another slide with the collapsed menu, the screen looks cut-off as in the attached image, I can scroll down and to the sides, but this shouldn't be this way, is there a way to avoid this?

This happens with lots of my trainings.
