Probation End Data not inherited in records post hiring

Content (please ensure you mask any confidential information):

Hello experts, we have seen that for many employees they have on the Hire record a specific probation period and, as a consequence, a specific probation end date. However, for the historical records created after the hire date the probation end date is no longer visible, the field is blank. The Probation Period keeps to be visible. Has anyone faced the same behavior?

We have tried to reproduce the same scenario manually and the probation end date gets inherited for all the updates made post the Hire date.
