My HQ 4 Account on Objective #8 has to Destroy 9 Mortar Turrets but when I (using my HQ 4 Account) destroy said Turrets it DOES NOT REGISTER!

I have tried re-booting several times but every time I attack and destroy Mortar Turrets I get no "Task Credit" so effectively I won't be able to complete Event and my HQ 4 Account is stuck on Objective #8.

I too will be reporting this to Disney.
UPDATE: I opened Support Ticket Number 05334551.
UPDATE #2: Issue Has Been Fixed - See my post found here.
