Entitlement's Audit history has an event of "Reject"

Hi All,

I just happened to see the audit history of my entitlements and found something really weird.

In the screenshot provided I can find some events of "Reject" and "Activate" and found it really weird. (Microsoft Dynamics CRM 2015 - 7.0.0.3543) This seems to happen when I enter tasks into my case.

I tested in my test environment (CRM 2016) and it has a completely different audit.

There is not activate or reject, only update.

I appreciate any insights can could be provided.

Thanks for your time!!!
