Storyline blocks adding to large file size

hello;

I have a rise course that I needed to incorporate affirmation check boxes to ensure people have read specific links, etc.  I could not find how to do this in Rise so I put in simple storyline interactions that just say "by clicking this button I affirm that I have read and accountable,blah, blah".  these interactions have taken an 8mb file up to 28mb though and now it is not opening correctly in Moodle.

A) can anyone help me with a cleaner way to do this affirmation in Rise?

B) is it normal for small storyline interactions to increase file size like this?

Thanks

Tim
