This problem still persists. There is no extra grey image in the options section. I have deleted all images and videos multiple timer. Everytime I upload, after few minutes some image or video goes blank and a "cloud" icon stating the image is submitted, in the process of upload or something on those lines. It never gets uploaded. This is definately a bug and preventing me from submitting my first game. Google play store is confusing but not laggy like Apples. Very bad experience so far.
