P: Graphical Watermark not visible on image in dialog but is visible in Export preview

Hello! I updated to the Lightroom 6.3 version and now I can not add my graphic watermark. I was able to last night but now this monring after the updated I am no longer allowed to. I can use the text watermark though. I don't know if this is a bug or if it's something that's new. Please let me know if it's something I need to fix on my end. Thank you!
