Links page is not working properly

[ruby-kim]

I want to add links in Links page,
so I copy files from pure/_source/ to myblog/source.

and I edit _data/links.yml file like this:

I can't see anything when I run in the server(localhost:4000) at first.

However, if I edit even one letter and click the refresh button(F5), the site appears.

So when I deploy it, the site doesn't appear properly.
How can I solve this?
Thank you :)
