After defending a Haven of the Anu, and receiving an Iconoclast shotgun as loot, I could see that the text is overlapping on the item preview. See screenshot.
ALL items listed there as loot had overlapping text on the first statistic of the item I was looking at, when mousing over them. It wasn’t just the shotgun; it was every item there, the medikit, the ammo, and the shotgun.
To reiterate, the same first statistical line after the name/description header of the item was doing this, for all three item types, in that haven defense summary window.
