Black background in regions

Hello. The region’s on my display show a black background. I have a CSV dataset in one region and embedded HTML in the other. It previews with a transparent background (which is what I want) but appears on my displays with the black background. I attached an image for reference.

Is your background image a PNG file?

If so, that’s not supported on a Windows Player. You’ll need to swap it for a JPEG background image, and then restart the Player to clear it.
