Adobe Portfolio Frustrating!

It was supposed to be an easy way to publish a portfolio website.

I designed it and published it.

Now the masthead buttons are suddenly non clickable. They still work on the editing site.

I don't know how to work around this problem.

I also have a stubborn masthead rectangular shape at the top of my site which I cannot take away.

The mobile site also looks so messy. Wish there was a way to adjust even just some small parts of it.

Help will be much appreciated.
