Drop cap sort of works only not really

I found an answer on the forum about how to insert a Drop Cap. I did what it said, and the letter is bold, but it isn’t drop-capped. What do I do now?

Drop caps only work when they can span more than one line. In single line paragraphs, you won’t see the effect. If your drop caps are in longer paragraphs, please give more information. You should at least mention the version of LibreOffice, and tell us how you set the drop caps. Please remember that we can’t see what’s happening on your computer. You have to tell us.
