Missing Button in Big title section

For some reason the button that is supposed to be in the big title section has completely disappeared. This occurred when I tried to hyper link one of our pages to the button. I have tried a variety of things to try and solve the problem. When I try and edit the Button through the Big title section it seems like something is happening because the page is refreshing but its still just gone. I would appreciate help thank you.
