I cannot remove an recipient on my JotForm

I am trying to remove a recipient on my JotForm, but even after I remove them and save the recipient remains, here is the form:

https://www.jotform.com/build/70368446053154/settings/emails

The email I want to remove is "chris.alp@yesiamgraphics.com" from receiving email submissions.

Again, I click the "X" next to the email, it disappears but when I click "Save" and then go back into the recipients, it still remains.
