Finished SM Quest but can't turn it in?

I already submitted a gm ticket on this, but in the interest of time, was wondering if anyone else had a workaround for this. I hit 50 shards mid raid, went to turn it in and the "continue" button is greyed out even though I have 50 shards in my bag plus SE. It shows completed in my quest log as well.

You probably need to do the classic abandon and retake.

Just gotta write that in-game ticket and wait, you'll get your SM then.
