TXT record not deleted from /var/lib/bind/db.<mydomain>

[6zmqfnftrh@…]

Upgraded to:

DHCP Service 2.2.1 DNS Service 2.2.1 and rebooted.

When I go to DNS -> "TXT records" of my dynamic domain and press the delete icon (garbage can) for a previously entered TXT entry, the following message appears on top of page :

An internal error has occurred. This is most probably a bug....

...and In zentyal.log: 2011/10/28 14:27:41 ERROR> Union.pm:393 EBox::Types::Union::AUTOLOAD - Method printableValueByName is not defined in type select

After that "save changes" appears, I apply it but /var/lib/bind/db.<mydomain> remains the same e.g the deleted TXT is still there.
