Parry on Elektra not working

Parrying Elektra doesn't work. Was exploring 4.2.5 The green colored "Parry" pops up when contact is made. The only node is a global node which is not stun immunity. Parrying works against other champions. This is after the emergency maintenance.

No debuffs on me at the time. Had power flood as the random buff. She did not land a hit on my champ to give me a debuff.
