Thank you very much both of you. I was able to fix it with Whiz's reply. I do not know why photoshop did that. I only created a background layer and filled it with the gray color. So I don't understand why that happened. But it was like it had a bevel effect on it. When I fixed the sides I noticed it at the top too. Anyway it is all good now. Thank you so much you both have been a big help.
