Hard to know without seeing the html for the menu. If the page is online feel free to post a link to it.

Based on your css what I think is probably happening is your home page link has the current_page_item class hardcoded on the link. You need to test to see if the page is the home page.

If you are testing then it's possible WordPress isn't doing quite what you think. For example you might be testing for is_home() when you should be testing for is_front_page()
