dragon age 2 quest act of mercy

I am playing Dragonage 2. I completed the quest "Act of Mercy" around 5 hours ago. I am ready to move on and do the main plot but the quest Act of Mercy is still under the rumors tab which prevents me from moving forward with the game. I have done research online and this is a bug because I am done everything that I needed to do to complete the task. Please help.
