Stun & Elemental Ailment Threshold stats?

After dying a couple of times in juiced T15 maps where mobs have + Freeze Threshold, I decided to drop 3 dmg nodes and invest a bit in Elemental Ailment Threshold.

I selected the Unbreaking node + a Jewel node and bought a Jewel with +20% Elemental Ailment Threshold on it, for a total of 50%.

Upon equipping them though, I noticed that in the Character panel, nothing changes.

So my question is, are they working, but just the character panel isn't displaying them or are they not working at all?
