New icons are not showing

[Yuhsuan Cho]

Hi guys,

My first 5 icons are showing well but then the others I added ( not replaced ) are not showing in my local index file. They are showing in the file folder that we downloaded ( icomoon-v1.0 (n) ) but for some reason disappear when I drag the new font folder and style.css to my working file. 

I can see the new icons are there because there's css code in inspect. ( see below )

I wonder if it's a cache problem or something. Does anyone have the same problem like this?
