Packages won't update on account

I have three accounts, two packages. While I can assign any package to any account, there seems to be no changes when I do so. No update of disk or bandwidth quota. It's as if no change occur at all, although CWP says the change is successful and displays the correct package.

I have no idea what else to try. That's a pretty basic function, I can't see why it wouldn't be working as intended.
 

Have the same issue.

However, when I do:

1. Suspend account
2. Unsuspend account
3. Restart CWP

the limits of the account become correct accordingly to the specs of the applied package.
