Hi,
it makes sense. By filling the form you modify the document, which
invalidates the signature, because the signature validates the document
in certain state. You should sign the document only after the form is
filled. If you undo your changes in the form fields the signature will
become valid again.

I cannot speak about this one, it depends what you use for saving,
eventually whether it claims any reason why it doesn't want to save the
document. I think it doesn't matter, though, due to the above
paragraph.
That said, your change in the PoDoFo can be valid and fully correct;
The "weird" behaviour you see isn't influenced by your changes in the
PoDoFo.
Hope it helps,
