Email Signatures Missing From Reply and Forwarded Messages

Email signatures do not work for reply and forwarded emails. Signature work normally for emails I write. I have 4 email accounts and 3 HTML signature identities. For each account I've enabled signatures for reply and forward in the Composition and Addressing menu option. I've tried restarting TB in safe mode by holding shift key. Nothing works. I cannot use signatures for any email accounts or identities for replies and forwards. Help please. Something is broken. I have latest version of TB.
