Tell me, please, If I have a object inside another object, both with a arraylist structure, how do I remove one property?

Here is my exemple:
#How do I remove $register[$I].item.value

$register = [System.Collections.ArrayList]::new()

$register.Add( [PSCustomObject]@{ item = New-Object System.Collections.ArrayList } ) > $null

$register[0].item.Add([pscustomobject]@{attribute = "1st";type = "1st-Type";value = "1st-Value"}) > $null
$register[0].item.Add([pscustomobject]@{attribute = "2st";type = "2st-Type";value = "2st-Value"}) > $null
$register[0].item.Add([pscustomobject]@{attribute = "Add";type = "Add-Type";value = "Add-Value"}) > $null
$register[0].item.Add([pscustomobject]@{attribute = "4th";type = "4th-Type";value = "4th-Value"}) > $null
$register[0].item.Add([pscustomobject]@{attribute = "5th";type = "5th-Type";value = "5th-Value"}) > $null

$i = 0
$j = 0

$do_loop = $true

$register[$i].item[$j].attribute

$register[$i].item[($register[$i].item.count -1)].attribute

While loop

While ($j -ne $register[$i].item.count)
{
if ($register[$i].item[$j].attribute -eq "Add")
{
$register[$i].item.Add([pscustomobject]@{attribute = "3rd";type = "3rd-Type";value = "3rd-Value"}) > $null
}elseif ($register[$i].item[$j].attribute -eq "3rd")
{
$register[$i].item.Add([pscustomobject]@{attribute = "WORKED!";type = "WORKED!-Type";value = "WORKED!-Value"}) > $null
}elseif (($ffff -eq $nulo) -and $register[$i].item.count -eq 7)
{
$register[$i].item.Add([pscustomobject]@{attribute = "NULO!";type = "NULO!-Type";value = "NULO!-Value"}) > $null
}elseif ($register[$i].item.count -eq 8)
{
$register[$i].item.Remove($register[$i].item[7])
$register[$i].item.Add([pscustomobject]@{attribute = "NOTNULL!";type = "NOTNULL!-Type";value = "NOTNULL!-Value"}) > $null
}

Write-Host $register[$i].item[$j].attribute "=" $register[$i].item[($register[$i].item.count -1)].attribute

$j++

}

Write-Host ""
Write-Host "[5]" $register[$i].item[5]
Write-Host "[6]" $register[$i].item[6]
Write-Host "[7]" $register[$i].item[7]

$register[$i].item.Remove($register[$i].item[6])

Write-Host ""
Write-Host ""
Write-Host "[5]" $register[$i].item[5]
Write-Host "[6]" $register[$i].item[6]
Write-Host "[7]" $register[$i].item[7]

Write-Host ""
Write-Host "all:"
foreach ($for_each in $register[$i].item)
{
Write-Host $for_each.attribute $for_each.type $for_each.value
}
