I assume you are referring to the different categories for the forum? Are you on a tablet or phone?
I noticed on my tablet in the 3 bars next to the cakesdecor logo I only get the option to view all the forums but when I am on my laptop and choose forms I can choose which category I want to view.
I have not figured out a way yet to do this on my tablet, maybe someone else has and could share, but I hope this answers your question.
