Editing a name in Sitebuilders View Page drop down menu

Hello . In my Navigation Menu I have a Tab that says Home Page Pays. That info is ok but that page was used before for Zeek Rewards and so now when I look in site builder drop down menu next to the View Page it still says Zeek Rewards Zone. I cannot change it .any idea how to just change what shows in Sitebuilder menu please. The Navigation Bar shows the right name.
