FluentForms form refusing to send email notification

I have 11 total forms that all function, send out emails using FluentSMTP, and logs all show the emails sending correctly without any alerts of the emails failing. Those forms all email correctly and show it correctly on activity logs.

But, I have 2 forms that gets used the most, that although I have the exact same email notification setup, have recently started not sending email notifications. 1 of the forms uses google sheets integration, the other simply just collects data and emails. The information from the form using the google sheet integration does end up on the google sheet, but the email notification is both of those forms has stopped sending emails.

On the forms that work and push email notifications, under the entry it shows the submission log as it should.:
info in EmailNotification (Email sending initiated) at 2026-10-08 15:52:57

On the 2 that don't send an email, it's blank, but the email notifications settings are exactly the same as the ones that DO work.
These forms used to send email notification until about a week ago around when I ran the recent plugin update, but that doesn't explain why the other 11 forms work and these 2 don't.

• If I use the "Resend notification" button on the entry that didn't send it does properly send one, but why isn't it sending it the first time all of a sudden?

What could cause 2 forms out of 12 to not function when it's setup the same way?
