Two "HOME" navigation links showing

Thanks for the good job you are doing there.

ISSUE 1

After installing the Business Point theme, I noticed there was “HOME” and “SAMPLE PAGE” navigation links. I was able to delete the SAMPLE PAGE but did everything to remove the “HOME” without success. I moved on to customise the Home Page by going to pages, the Reading to select HOME, after this, I noticed the HOME navigation link became two. I tried to delete from menu but customised my Home Page went off. I tried to remove it from All Pages, but my customised Home Page still went off again. What do I do?

ISSUE 2
Is it that Business Point theme can not take more than 5 pages? I had 5 pages already, the moment I created another page which is “contact”, one page or say one nagivation link disappeared. How do I solve it?

Thanks for your anticipated quick response.
