Forum Name and description in phrases

[LICryptkeeper]

hey, I've tried making a custom phrase (forumname_offtopic and forumdescription_offtopic) with two languages (english and french) and would like to have the output of the forum name resulting in the english or french language.

I've tried changing the forum name in "create new forum" as "$vbphrase[forumname_offtopic]" yet it outputs it as $vbphrase[test_language_forum_1], not as "offtopic"

what else do i need to change, I'm assuming that I will either need to edit something in a template, or in a file, I've tried searching the answer for about 30 minutes, but I'm assuming I'm using an insufficient query.
