Domain of Istan - Sunk Cost achievement not progressing

[Delita Silverburg.8632]

I looked to see if anyone had posted this already, but it seems not. As the title states, the achievement for Sunk Cost within Daybreak in the Story Journal does not advance regardless of how much damage you may do to a named ship. Over a week ago I got credit for one of the three, but after about 10 differen Palawadan metas, I haven't had any further progress. They fixed the Istani Bounty hunter one, so that's cool, but this is literally the only achievement i have left on the map now. Please look into it, thanks!
