The seal is stamped from the back and readable the way it is stamped (from the back). Then the registrar signs in the middle of the seal (on the back where the seal is readable). When we look at the photos of the front of the document the seal appears backwards and is not signed.

Did you mean the document is signed and then the seal is crimped into the paper over the signature?

It’s a lot easier, neater and more natural to sign on a smooth flat surface.

My seal is stamped from the front, see, isn't it pretty?

I wouldn't have charged the campaign a penny for this either :P
