Presenter 360 and Scroll Bars

IGNORE THIS - it was just the LMS Preview screen.  The course loaded ok when taking it as a user. 

I am probably missing something obvious, so thank you in advance for any support.   I published new content today and loaded it into my LMS system. 

Currently, the user needs to scroll down and to the right to see the NEXT button.   How can I fix this?

Due to the equipment people have, the player template it is going into is a height of 668 and a width of 950.   The slide size in PowerPoint is 4:3.

I don't remember having this with other trainings, but can't remember what I changed/fixed so it did not occur.

Thank you so much.
