Transparent Buttons Move in LMS

Hello,My Lectora users create a lot of transparent buttons to generate pop-ups. They work fine in Lectora. However, when I publish to my LMS (which is Saba), the transparent buttons move. They are no longer on top of the appropriate text. Usually, they move below the text. I have not had this problem before, but it's happening with my 2 most current trainings. I'm trying to find differences, but I find none. Is this a resolution issue?
