Unable to select category

This morning, after I did some listing I went to list another item, using a template of another listing. I noticed that the Category was showing as “Unknown” and when I click on the category to select the correct one only the top level categories appear.

I’ve tried closing garage sale and re-opening it but the same thing happens.

Ok, I’ve solved it. If I updated the categories it was OK. I didn’t know that button was there!
