Email Tags dissapearing

Hi,

Email Tags are not showing anymore on old and new form, causing validation error.

With the default content :
From : [your-name] <[your-email]>
Objet : [your-subject]

Corps du message :
[your-message]
—————————–
The field reply to :
Reply-To: [your-email]
Is showing an error “invalid syntax”.

Thanks in advance.
