Contact Form 7 emails arrive with field codes but no user data

I use the same simple form across multiple pages on my website. Starting on Friday, I noticed that I received an email that someone completed the form, but the email contained no information. I provide a sample email below.

I replicated this behavior by logging in to my wife’s computer, completing my form, and submitting. The email below arrived in the inbox.

I have not touched anything about the forms or the pages that they are one in weeks. Recent WordPress updates seem a likely culprit.

Any help you can provide is most appreciated. Thanks.
