They do not exist, so there's nothing to create - take a look, when you follow the link the page says 'create'. There is no way to prevent people from adding non-existing categories (but we can always see who is doing it throught the mesage and tell them to stop/do it better). And wikia software which badly needs an update is showing non-existing categories as blue links, which is confusing (Wikipedia would properly show red), but again, this is out of our hands regarding when/if they'll fix this bug.

Thanks for taking care of the categories!
