Apart from Randy's observation, are you saying for example a JPG of a signature was pasted onto a form and was not centered correctly, or was a tablet and pen used and the signature was made outside the capture window?
I think the important part is that the affirmation boxes were marked you can attribute this to your applicant/borrower. The signature itself could be used to compare to what your customer uses and the more of there the better. But at the end of the day it isn't as though any signature that is shown as incomplete would be analyzed against what your customer uses since an e-signature is any electronic process that indicates acceptance of an agreement or record. What you have may be questioned and look bad if it's incomplete, but I think only a qualified attorney could tell you if what you have would/should suffice based on your procedures.
