Bug - stun not showing up

[Francy333]

First of all ty for creating this for classic.
It works really well, but I've just encountered one bug. It's not showing the cc debuff on the unit frame for this specific weapon : Earthshaker.
It is a drop from Molten Core and has a chance on hit to stun all melee aoe targets for 3 sec. Unfortunately its not showing up.

Would it be possible to add it?

Thanks!
