This is a known issue and will be looked into as soon as David is done with vBNotifs.
Here is a workaround if you must have it up and running.
I got it working for now, I had to make a new category and it works from there, the category N/A on there do not delete it, the moods will be in the category Blue.
So basically make a new category called Blue2, add the moods to that one, and after that re name the first category N/A.
