How to setup a list to use item level permissions - SP 2013 - Need Help

Question

Hi All,
      I have a created a group called TeamGroup in a site collections and i have all the users i the site to this group.
Now i have a subsite and in the subsite is a list i want to configure list item permission for.
For users to get to the subsite the TeamGroup has been given access to the subsite unless they wont have access to the list inside the subsite.
The list has been configured to use unique permissions.
But any time i add users dynamically to the list item(Read Permissions) it also adds TeamGroup(Read Permissions) to it :(
Im using powershell to add users to the list time which also breaks the inheritance.
So when users browse the list they also get to see other items because the TeamGroup has been added.
How to set this up?
Thanks in Advance

Ok i can try removing the user from the group an would give it a try.
When you say "when break the inheritance did you remove everybody from the list?"
What do you mean can you elaborate?
when break the inheritance did you remove everybody from the list?
if ($item.HasUniqueRoleAssignments -eq $False)
$item.BreakRoleInheritance($True)
#$user = $web.AllUsers[$UserName]
$roleDefinition = $web.RoleDefinitions[$PermissionLevel]
$item | ForEach-Object {
#Write-Host "ItemID: " $_['Contractors']
$spuser = $_['Contractors']
#ForEach ($user1 in $spuser)
#Write-Host $user1.User
#$roleAssignment = New-Object Microsoft.SharePoint.SPRoleAssignment($user)
$userId= $spuser.Split(";#")[0]
$account=$web.AllUsers.GetById($userId)
#$domainName=$account.LoginName.Split("|")[1];
Write-Host $account
$roleAssignment = New-Object Microsoft.SharePoint.SPRoleAssignment($account)
$roleAssignment.RoleDefinitionBindings.Add($roleDefinition)
$item.RoleAssignments.Add($roleAssignment)
