Hi @kearsan
I’m afraid I couldn’t reproduce this issue on my end. Do you have a custom function to handle the form? Could you please try to reproduce the issue on one of the WordPress’ stock themes (like Twenty Fifteen) with other plugins deactivated? If it disappears, then you can activate the theme and plugins one by one to see which one causes the issue.
Also, could you please share the PHP file where you show the ACF form?
Thanks!
