I have this exact same issue and I opened a case with Microsoft tech support on it. Their answer was that this issue is fixed with the latest update rollup patches. I am on SP1 UR2 so they basically said this issue was fixed in UR7.

You can also use this:

Import-Module OperationsManager
#get the duplicates
$Values1 = Get-SCOMClass -Name Microsoft.Unix.OperatingSystem | Get-SCOMClassInstance | select -ExpandProperty Path
$Values2 = Get-SCOMClass -Name Microsoft.Unix.OperatingSystem | Get-SCOMClassInstance | select -ExpandProperty Path | select -Unique
$result = Compare-Object -ReferenceObject $Values1 -DifferenceObject $Values2
#to remove the agents
$SCXagents = $result.InputObject | % { Get-SCXAgent -Name $_ }
$SCXagents | Remove-SCXAgent -Verbose

We have the same issue. All servers on 2012R2 UR8. We upgraded from 2012sp1 UR5 4 weeks ago.
