Added already fields found missing from the admin panel and problem to add the missing field with the same name again. I suppose there could be some problem in the frontend of the field administration page.
If you look at the list now, i'm able to add a charge move. I added Shadow Sneak to the list and it is showing up. Right below Zap Cannon you should see shadow sneak as well as it is showing up on Spectrier's post.
