categories

Hi-

I have two blogs and I need to select categories which fall under each blog. However, when I go to the blog page, I am only able to select two categories out of the nine categories that I created. The drop down selection on the blog page is only showing two categories and not all nine. Can you help with fixing this or maybe let me know where I am getting this wrong…

I am attaching a screenshot to support what I am referring to.

Thanks for your help!
