Order sorting bug

I just been going through and trying new things. Love the new look but have noticed a few bugs. Did a upgrade to stable and noticed when under 'Mailbox quota' and want to arrange the mailboxes by 'Used space' it does not display any results... Also when using any of the order sorting other than the domain or linux user in 'Web traffic' or 'Website hard disk quota' it don't order correctly..

Ive noticed it used the first number to sort it out if that helps 😄
