Service Names are different, though same version, CRM 365 On Prem

We installed CRM 365 On Prem on four servers, two front and and two back end, and I'm noticing some of the service names are different.  For example one server has "Dynamics 365 Unzip Service" and the other has "Microsoft Dynamics CRM Monitoring Service".  The version is the same for both though one server shows 8.2.1.176 and the other is 8.2.0001.0176.   We installed both from the same media and ran the update to 8.2.1.176 afterwards from the same file. 

Any suggestions on what happened?  And will this cause any issues?

Thanks.
