Is this a link, or not?

Hi, all!

This is part of a passage's code (the meaning of the French words is not important):

(set: $grille01 to it + 1)Voulez-vous [[[b]continuer à pousser la grille[/b]|Grille01]] ou [[[i]abandonner le jeu[/i]|Abandon]] ?

The bold text and the text in italics are both links, and they work as such. Yet the bold text is not displayed as a link, it has another color. What is it and how can I give it a link's color? I'm using Harlowe 1.2.4.

Thanks in advance.
