Me -> Team Schedule: Other than Line Managers, some random employees are getting displayed

Summary:

Hi Team,

Employee Login: Me → Team Schedule. If we click on Show filters, under Line Manager heading, along with actual Line Manager, some other random employees are also showing up.

Our client wants only active Line Manager should get displayed under Line Manager heading.

Ideally only one actual Line Manager should get displayed under Line Manager heading.

Could you please help me from where the random employees are coming and from how can we control that.
