Cursed Ring?? - Stats decreasing when equipping a ring

Bug Report ID: #2965311251

When equipping RING_1 my stats are decreasing - I lose DPS and evasion rating on the tooltip. This decrease happens even when I equip the ring on an empty slot - meaning I'd be better running no ring, rather than this ring. It seems as if the ring is decreasing my stats rather than increasing it.

I have the exact same issue with a ring that has similar stats. When I equip the ring I lose a fair amount of dps on all skills. The defensive stats appear to be applied correctly in the character info.
