Hyperlinking

I'll get right to the point. @Tony
I'm not sure why but some of the titles on NU are either not getting hyperlinked or getting hyperlinked in a random manner.

Eg : A Record of a Mortal’s Journey to Immortality
I’m Really a Superstar
Renegade Immortal
Ark
Martial World

Spoiler: Warlock of the Magus World (No BB Code Used)

As you can see WMA got hyperlinked.

Spoiler: Warlock of the Magus World (No BB Code Used Once Again)

Now it doesn't get hyperlinked :-/

To re-check if it was a mistake on my side (typos or spacing mistakes) I copy pasted all the titles by visiting the NU pages of respective novels.

P.S : I am no techie and I don't exactly know how this hyperlinking works. So please don't bombard me with technical jargon while replying. Maybe it's a huge mistake on my side after all.
I just posted what I found as a user.

 

I tried writing Warlock of the Magus World in the thread where it worked to check if it was related to the subforum but it didn't work. I've never actually had a single novel that turned into a hyperlink.
