【Task】 I'm configuring a task for a specific group of users; why was "invalid user" displayed?

Invalid users will be displayed in the following situations:

1. The employee ID was entered correctly, and the account has already been activated in-app, so why was the user displayed as invalid?

Answer: Please check to see that there are no spaces or empty rows after the employee ID.

2. The employee ID was entered correctly, and I only entered one, so why do two invalid users show up?

Answer: Please check to see that there are no spaces after the employee ID and make sure that the following row is empty.
