Qlik Data Integration Pipeline Project Internal Server Error when opening Register Data Task

I have two Register Data tasks in a QDI Pipeline Project:

DEMOGRAPHICS REGISTERED (not working)
DEMOGR REGISTERED NEW (working)

Both tasks are configured identically; however, when task #1 is opened, it shows the following error:

Operation failed Internal Server Error Error code: DATA-APP-DESIGN-DB-COMMANDS-OPERATION-ERROR

When prepare is launched for task #1, the following error results:

Failed to prepare Data task 'DEMOGRAPHICS REGISTERED' in project 'QTC E2E Customer Churn' - 'message: Failed to get metadata for data entity 'registered_dataLANDING_demographics', data task 'DEMOGRAPHICS REGISTERED' in project 'QTC E2E Customer Churn' Error code: DATA-APP-DESIGN-DATA-TASK-PREPARE-FAILED

So, my goal is to either:

Repair task #1 such that it works just as task #2 does
or
In the task chain, replace task #1 with task #2

However, I do not know how to accomplish either of these goals, and would appreciate any relevant guidance!

Thanks,

Jeff
