Solas Quest - Measuring the Veil, cannot complete, bugged?

I had the same issue, I managed to complete the game without doing since its a inner circle quest, besides the lore and romance you should be fine otherwise you'll just have to wait for a patch or alternatively go through the struggle again.

Here's a picture probably of the same issue:

Edit:

This is on the PC if an EA staff views this.
