I just called tech support about this and was told to use white out.  Seriously?  My issue with this is that even though I give clients envelopes with the correct address, it looks unprofessional to me that the voucher doesn't match the envelope.  And using white out, or putting another label over it, would look worse than leaving it with the wrong address, not to mention the extra time that would take.  I don't understand why this has not been updated yet since the change happened months ago.  At the very least, there should be an option to edit the address, or a box that lets us choose to use the new address even if the instructions haven't been finalized.  I don't trust the post office to forward any of these payments so feel strongly that the address should be correct.  The tech support person told me that they are just now, in the last couple of days, getting calls about this.  Sounds like it wasn't even on their radar.
