Ex-employee is still showing up as employee on the Candidate list

Summary:

Ex-employee is still showing up as an employee on the Candidate list

Content (please ensure you mask any confidential information):

An employee has applied for a position, in a meantime his employment has been terminated due to the end of the contract. The other terminated employees are showing up as ex-employees, but this one is still listed as an employee on the Candidate list. Everything is fine in Person Management, termination done correctly. All the related jobs are scheduled and running in production. We've tried to run "Load Workers into the Candidate Table", but this did not help.

We ended up removing the person from the requisition, updating his record via HDM and then processing, but is there an easier way to handle cases like this? Please advise.
