Unable to display images on AI Companion (Android Tablet)

I am new to App Inventor and trying to layout my first screen. I would like my buttons to have various shapes and decided that images would be the best way to handle the requirements.

I first created the button and uploaded a .png and a .jpg from my pc to App Inventor. When I select them on the images they appear as desired on the App Inventor application but when I connect to the tablet, the images do not display.

I did a search of the site but did not find any posts with this exact problem.

I tried adding as images as well but with the same results. Not sure what I am missing but no matter what I try, I can not get an image file to display on my AI Companion.
