So I looked up your stats, and I think the problem is that you haven't collected 45 Calcified Fragments on a single character; each of your characters have different fragments collected. Your Titan only has 40/50 Fragments. This is shown in-game when you go the the map of the Dreadnaught.

You can see which of your characters have which fragments here:

Pick up five more Calcified Fragments on your Titan and you'll get the next step of the quest.
