Smart Shape Button area partially enabled

I'm having a similar problem with smart shape buttons.  I do have the latest version of captivate 2019 11.5.1.499.  I created a rectangle with rounded corners, changed the fill, added text, changed the colors on the state view.  The buttons are only to navigate to next slide and back.  In testing within captivate, the buttons worked fine.  When I publish to LMS sandbox, only the bottom 1/4 of the button is clickable and show the state views when rollover or clicked.  The rest of the shape is useless - no action happens when clicked or rollover the top 3/4 of button.   I only publish as HTML5 as that is what I was instructed to do to solve other issues with captivate and our PeopleSoft LMS. 

To troubleshoot, I deleted a couple of buttons, and inserted new smart shapes as buttons, but same problem.  I inserted a traditional button, and that works just fine.  I have been looking over the internet for similar issues, and except for this thread, I've not found anything similar.  Any help to understand/fix this would be appreciated, otherwise I'll have to delete the shapes and replace all with traditional buttons.  😞
