Websites Do Not Reflect Changes made to Blog Template

I have created a blog and used that to create a Blog Template called "Project Master". I have created another blog which uses the Project Master blog template. However when I make any changes to the Project Master site (such as adding new pages; editing content in existing pages; settings etc), it does not reflect to the sites based off that template.

In the blog template settings, I have ticked all the checkboxes to update the pages, settings etc.

Is the blog template supposed to dynamically update all sites using that template? If so, how do I make this happen?
