Mail (2) Doesn’t Get Sent

I’ve recently updated to WordPress 5.0.2, running the latest version of Contact Form 7 (5.1.1) and Google reCAPTCHA Version 3.

I’ve noticed that my forms will send emails to “Mail” (which sends to myself), however it doesn’t send any emails to “Mail (2)” (email to the client).

I haven’t changed anything in any of my older contact form settings, but noticed this when I tried to make a new contact form after testing it. None of my contact forms send emails to “Mail (2)” anymore.

Is there any way to resolve this?
