How do I change the Prefix to an existing thread ?

I opened this thread a few months ago
https://www.ownedcore.com/forums/mmo...s-free-sr.html (⭐ RX9T Boost ⭐ 100% Positive Feedback ⭐ Top 500 ⭐ Cheap Prices ⭐ FREE SR ⭐)

Now pretty much every other thread had the Boosting prefix to it except mine. I tried changing it but I could not find anything.
Also upon editing my own thread I get this error "You do not have enough CoreCoins to edit thread title". I figured I just had to edit the first post in order to change the Prefix. Does that mean I need 1000 CC for that too ?

Hi RX9T,

You should be able to edit your thread's prefix without needing to spend any coins. Nonetheless, I went ahead and changed it for you.
