Why won't my automation trigger when a contact joins a segment?

I am having trouble because my automation is not working,ย  it is set to trigger when someone is added to a specific segment. No one is being added to the automation even though I have contacts added to specific segment.ย  The contacts is coming from Facebook leads and their status is subscribed.ย  How can we fix this?ย
