Unable to find "Field Styles" under my Preferences tab to remove highlight

I'm facing the same issue, and am unable to find "Field Styles" under my Preferences tab as I suspect Jotform has updated its layout since this this answer was last posted. How can I get around this problem?

To remove the highlight on your form, you can edit/change it in the Designer mode. You will just need to set the background color of the highlight to transparent. Here is a sample demo to remove the highlight effect in your form.
