Canceling issue

When I put the description of the image I wanted, it moved me over to another page asking about all the other details, etc, but what it didn't let me do was click cancel when I was picking the model version. I had confirmed one but it didn't do anything, it had just stayed the same except that it didn't let me click on the confirm button, so I clicked on the other model and the same thing happened so I just clicked cancel. It wouldn't let me cancel. It wouldn't let me not pick a model even though it still made me keep clicking the same models over and over again if you get what I'm saying.
