problem with template mailbox quota

[pixel]

when I try to creat or edit a client template or domain template
I face problem with "Set the mailbox quota" Option it's only support 6 digit Numbers NO more thats mean for mailbox quota its only support 999999K.Byte No more
but if I tried to do it from Limits Options for cients or domain it's working fine i got 9 dig 999999999K.Byes.
