"Home" link in category tree link is incorrect

[grannynel]

I'm a total newbie here, so please bear with me if my terminology isn't correct. I am using PS 1.7.4.3. I enabled module Category Tree Links and configured it like this:

Category root: Home category

Maximum depth: 0

Sort: By Name

Sort Order: Ascending

In Front Office, when you click the link "Home" it takes you to "2-home" instead of my actual home page.  What can I do to correct this? 

I don't want to start adding products until this is resolved.

Thank you all in advance for your help.
