Send Email - From Configuration

In one of our environments we are seeing some strange values in our From configuration drop down in the Send Email node.

The Sender value in the actual emails is also displaying differently than the way it is working in our lower envs (in lower envs, the Sender in the email shows as the Process Initiator display name as desired).

"From" values are showing as: ???address.process.displayName???, etc

Other envs look normal:

Any ideas what could be causing this?
