Cant access Other pages on my www.templatesold.com theme

ok so ive installed a theme called “timberdesk 1” by “ThemeLayouts/DreamTemplate” from the website templatesold.com. My problem is after i make changes to the entire webstie i am only able to see changes made to the home page? however i currently have a total of 4 pages, and have made changes to all of them why is only the home page showing live updates of all my code changes. also one of the 4 pages you see at the top titled “archives” shouldnt even be present i never created this page.

im not quite sure what the problem is but if anyone has experienced this before or knows how to fix it id greatly appreciate it my company runs on basic web development and this is kind of a “Cog in the Gears” as of now.
