Fill option is not working..help
So I was using the fill option on Photoshop CC 2015, and it was working fine. Randomly I went to fill in an elliptical marquee tool with a color and it ended up creating a white border around it. Then when I tried moving it, it would make my whole layer white (minus the elliptical. I have no clue how this happened. Please help..
Here are images of what it looks like...
