Bug when creating vouchers

[alltime]

We enabled vouchers and the default keys were added as the documentation mentions.  However, after Enabling vouchers and adding a voucher roll, all of the information was removed.  Now, no matter whether we enable or disable vouchers, we receive the following errors.

The following input errors were detected:

    The field 'charset' is required.
    The field 'rollbits' is required.
    The field 'ticketbits' is required.
    The field 'checksumbits' is required.
    The field 'publickey' is required.
    The field 'magic' is required.
    The field 'saveinterval' is required.

This is fine, but when we try to correct the missing fields, we can't because they are "grayed" out.
We've tried restarting the web GUI.
