Question marks (?) before item stat previews

1
Severity: Low: it's a bit annoying but it doesn't prevent me from playing normally;

Category: Interface

Frequency: Always present

How to reproduce: Open inventory and move the mouse over any of the items. You will see that there are question marks before the stat previews

Description: When moving the mouse over any of the items that has stats, there are question marks before all of the lines that includes the stat previews, e.g. if you have no pets equipped and you move the mouse over Lucky egg, the beginner pet, it is supposed to show LK: +1 and DP: +2, however it shows ?LK: +1 and ?DP: +2 (see below screenshot).
