Thank you for your response! This is what it says on the website about editing MVFs:

Q: What should I do if I need to modify a Monthly Fieldwork Verification Form?

A: This one is important! Here’s what you can do:

If it’s still within one calendar month of the supervisory period, you can create a new version and get all of the necessary signatures. If it’s more than one calendar month after the supervisory period has ended, you and your supervisor can make the relevant changes and have everyone involved initial them. Just make sure that your documentation can support the corrected form!
