Autoresponder email layout is not showing correctly

Why does the email content appear as it does below, in a narrow column? Illegible.
Thanks

Hi rtolmach,

Thanks for reaching out to Jotform Support. I checked a cloned version of your form but can't replicate the issue. Check out this screenshot of my result:

Can you try using another web browser in editing your form in the Form Builder?

Give it a try and let us know how it goes.
