This is because removing an item from the database will not automatically be removed from the ListView array of items.
If the items are selected in the ListView simply add these lines in the click event of the remove button:
For Each i As ListViewItem In ListView1.SelectedItems
ListView1.Items.Remove(i)
Next
This code will automatically remove the selected items in the ListView.
Another way to do this would be to delete all items from the ListView and then call the function you used to put all items in the ListView.
ListView1.Items.Clear()
ColocarItemsNaListView()
