I notice that the gambler font takes up sevaral times more space than everything else, to the point that it makes it hard to read the cost of items.
The font issue only applies to the text regarding the fact that it is purchased and not to any other part of the items text such as cost and stats.
I would post a screenshot of it, but the forum will not let me(and in game bug report forcibly closes the UI so it will not show the vendor trade window)
EDIT:Reloading the game fixed it
