Package won't update quota

So, I tried logging into a CP for a user, the UI complained with the dialog "Quota!"
I went to CWP and found that account to be overlimit for its allocation. I changed the package to a new, unlimited package I created for it. Not only will it not change, but somehow it got dropped to 1kb as its allocation...
It won't update no matter what package I use. As well, I noticed that changing other accounts had no effects either, their previous limits stayed exactly as it was.

Any insights, anyone ?

Funny I have this same issue. Just had to backup necessary files, delete and create new account then restore back. Seems its a bug on this panel.

You can also set packages in the root_cwp database. You could change the package to something else, then change it back to the preferred package with the correct quota setting.
