Slide Format Changes when Publishing from Storyline to Review 360

Hi, 

I have created a question bank in Storyline of 80 questions and plan to embed it in the main module created in Rise 360 with a randomised quiz of 15 questions following the primary content. The formatting looks good in Storyline, but when I publish to Review 360 the formatting on some of the slide’s change and the spacing is inconsistent. I have tried trouble shooting multiple times including changing the font to Arial, creating a consistent format across all the slides using Slide master and manually changing the affected slides - see example below of overlapping words on one of the slides:

I'd be grateful for any advice.

Thank you,

Erika
