There are a couple of reasons why your font may not seem to be functioning correctly. First, please check the item folder to make sure there are no specific instructions provided by the Author.
Secondly, it is important to check what program you are using the font in. Generally, word processing and presentations programs like Microsoft Word and Microsoft PowerPoint are not the best programs to use third-party fonts because it limits the options of the font's appearance. In fact, third-party fonts are not directly supported in Microsoft Office, so the swirls and glyph alternatives may not be available. More graphic-intensive programs such as Adobe Illustrator, Adobe InDesign, etc. are better choices for that type of usage because they are more equipped to handle the alternative features of your purchased font.
