Dovecot Quota Display Error

[asankaan]

Hi,

I'm using dovecot and roundcube based mail server and recently I updated dovecot to 2.2.34 .
After that, the quota display shows some strange behavior, i.e. it shows a percentage value aboue 100% (for my account, it is 19422%)

doveadm quota get -u asanka

returns

Quota name Type Value Limit %
User quota STORAGE 4661452800 24000000 19422

My quota limit is 25G and current usage is about 4.6 GB.
Repquota works fine.

Anyone has any clue on how to overcome this issue?

Thanks in advance.
