CMS Categories Automatically Nesting Themselves
 

I have a number of categories inside of a premium permissions section. They were set up like this:

Rankings
-Heat Rankings
-Top 50
Interviews
Team Reports
-Team A
-Team B
-Team C

I know this for a fact because I had to fix them because they were incorrectly nested within each other (I thought I had set them up wrong* but I'm doubting that now).

I spent much of last night adding old stories* and they were showing up the right way.

Today* they are now incorrectly nested:

Rankings
-Heat Rankings
-Interviews
--Team Reports
---Team A
---Team B
---Team C
-Top 50

The only thing I was doing this afternoon was trying to fix some permissions.

Anyone familiar with this problem or know how to fix this?
