Importing PowerPoint to Storyline - Font size an location changes

I'm just going to chime in here that my on-screen slides sizes have been coming in small.  16:9 ratio on both powerpoint and story file. For example, much of my ppt on-slide text is Gill Sans MT 18 pt but arrives in Storyline as 9.5. Possibly related, copying graphics from a master slide to a layout it arrives way too big (and often off the slide). I don't know if it's related, but I just tried to create a matching drop down question and the left and right side items overlap in the middle instead if wrapping to a second line. I created it as a matching drag and drop and it looks fine, but isn't 508 compliant.  I'm using Storyline 3.
