I recently added a new category to my list of categories. I tried to create an assignment and only the recently created category showed up on my list when I clicked on the down arrow for categories in the creation of an assignment box. The other four assignments that I had been using all semester did not appear. Please advise.
You may have inactive Categories. I would check to see if the "Show Inactive" button is checked. Go to Grading> Categories and look top right side of the screen. It is possible that a category may have been made inactive. I have done this by accident before. Any assignments under that category may be hidden when the category becomes inactive.
Please see the Help article to Modify Categories
