How to change the links and edit the Page Name under Sub Menu?

[Victoria21]

Hi!

I have been trying to change the page name as well as change the link of a sub-menu category but I cannot find the exact place to change the same. 

For example: Under my site: http://rakacademylpict.weebly.com/kg2-unit-5.html, I'd like that we had the title of the Unit on the sub-menu. How do we go about doing that? 

Also, I'd like to change the links on the sub menu pages. 

Thanks!

Do you see the Pages tab within the editor, @Victoria2? It sounds like you might be an editor of the site that doesn't have access to that. If that's the case, the site owner will need to make those changes.
