When you download a cheap template file without the suitable font, you will find that it looks different from the screenshot on the website. Because the template should work with the right font.

See this demo video:

When you have not the font, font in the template fallback to system default one such as Times New Roman, which is not monospaced font.

When you have the font, the template is OKay on everything. and looks exactly the same as in the screenshot.
