Text box text runs off page after publishing

I saw this come up several years ago, but this has been happening to me a lot lately.  I'll have a course that looks fine, I publish it to our LMS, and the text boxes are running completely off of the screen.  I publish to Review to test it, looks fine, but when I go to our LMS, the problem crops up.  I saw a question like this years ago, the solution was to set the Player Size to "Scare player to fill browser window", but I have that set for all of my courses.  This has come up in several courses lately...I was thinking it was happening to imported PowerPoint content, but then the problem came up in some quiz questions too.  I'm at a loss, I can correct it by going back into the course and reformatting the text boxes, but this is taking up a lot of time, and has resulted in courses going out with unreadable questions.  And advice is appreciated.  I am using the most recent update of Storyline 360.
