    Collision or duplicate entries... Things like that and Exchange will append a number to that object to prevent duplicates
    It can also happen if using AADConnect with UPNs and Proxies

    If you didnt add a samAccountName when you created the group, this can also occur:

    If that was the case here, you can always recreate it

    Hi @Efff dd ,

    I think you could go ADUC and check this group, group name, e-mail address.
    Or doing it in EMS: 

    Get-DistributionGroup DP1 | FL *Name*

    Like Andy said, i think you don't have to worry about it as you could modify these parameters manually or recreate the group. 

    Get-DistributionGroup DP1 | Foreach {Set-DistributionGroup $_.Name -SamAccountName $_.Name -DisplayName $_.Name}

    Regards
    Lou
