Content (please ensure you mask any confidential information):

Hello,

We have a candidate who had accepted the offer and is already in HR processed state, however now the candidate has declined to join hence we cancelled the work relationship and we don't find any profile active in person management.

However we do still find the employee still in HR processed state in req and even in manage job offer.

We don't want to delete the job application as then in future if we want to check on the candidates we offered this position to might not be visible.

Can someone help in understanding this ?
