Go View/Face Style and untick xray.

Thanks Box. It had been a while since i worked on it and I keep forgetting what things I changed. I quess I need to start making notes.

I did not know x-ray would stay on though in only one file

Xray is a style setting and will stay until you change it.

I think what mixed me up was that I have saved some Style settings to my Default Template and since they are in all my models. I was thinking that any changes that I made to Styles would stay the same in all my models. But I should have known that was not true.
