This morning we completed the upgrade and ever since when replying to any type of ticket, it ignores the requestor and cc information and does not populate any of the address fields like it once did.

Attached a sample screenshot... Have not applied any templates, but doing does not change the behavior. I'm not seeing any particular settings for this in the mail servers settings, notifications or reply templates.  Any ideas?

Thanks.

Steps for duplication, open any request or incident > click reply.
