Grant an Entitlement does not work as expected

Hello,

We are encountering an issue when attempting to grant an entitlement to users. The entitlement works as expected the first time, but when we revoke it and grant it again (as part of our test suite), the entitlement does not update correctly. Specifically, the old entitlement is still showing, and the expiry dates are incorrect.

Could you please provide some guidance on this issue?

As you can see below, the start and end dates do not match as expected.
