Powershell ListView using WPF - Items not showing properly - wpf

Question

Im trying to output into two columns the result of the following query:
get-mailbox -identity *#$SearchDomain | where ismailboxenabled -eq true
Here is what i've done right now:
$mailboxes = get-mailbox -identity *#$SearchDomain | where ismailboxenabled -eq true
foreach($line in $mailboxes){
$new = new-object System.Windows.Forms.ListViewItem($line.Name)
$new.SubItems.Add($line.Alias + "#" + $SearchDomain)
$WPFLstActiveMailboxes.Items.Add($new)
}
My problem is that things are showing up like this in my GUI:
Behind the black boxes is the data that I want

What I have always done is use databinding in WPF so that it is bound to the property that I want and then just create a psobject with those properties that I have bindings for in WPF, and then just add them to the ListView.Items collection.
Here is a reference of the wpf setup, and then just make sure to have your psobject properties the exact same as the binding properties in the wpf
