Mentions Plugin Issue

I had Mentions working perfectly and as intended when called would display a user's Display Name with a small Picture. I had this working with the previous versions of The Wire Tools and Mentions Plugin. Since then, Elgg 2.3 has been upgraded to Elgg 2.3.12 and so are the The Wire Tools and Mentions (Master) and Mentions (2.3).

Now, with Elgg 2.3.12 , Wire Tools (2.3) Ver 7.0.2, and Mentions (2.3) I am unable to make it work correctly, When a user is called @{username} it only shows user's Full Display Name and no image. Can some one please tell me what could be the problem?
