We originally did all the paperwork early in the new year then ran into problems and had to delay submitting it. Redid it all late July with what we tho't was all the new forms. Don't know why we didn't see that one. IMO the change of it adding Parent as an option is if there a same sex couple, one of who would check parent as opposed to Mother or Father? If that is the only change I can't see a problem using the old one. Sent it first week of Aug, they received it Aug 6.
If you re-downloaded all the forms in late July, it sounds like you got the right ones, and they must have changed from the "new" back to the old one sometime after June. I downloaded mine in early June, so I think you've got the most recent ones. I agree, I think it's such a minor difference it shouldn't warrant sending back a whole package, especially when they seemed to have swapped the forms so quickly. Thanks so much for helping clear things up and good luck to you!
