We'd love to help you make your Facebook post as great as you'd like! We would however like to clarify exactly what you're seeing. Would you be able to share with us a screenshot or a link to your post? I took a look at their account and can see you have added in the Subject Line Personalization to your social share post. Personalizations like this are meant for a subject line in our Third Generation Editor and will not display correctly through a social share post. Is it this personalization in your post that you are speaking about? Once we get these details we can help further.
