Remove duplicates but choose the old data to delete - excel

Question

I have this procedure that I have copied from a couple of forums and adapted to my needs. The procedure removes duplicates perfectly than copies my formatting as needed.
However, it is removing the new records that are duplicates and leaving me the old date.
I have a sheet with rows of data for loans and their statuses. The statuses change everyday and so I copy the new data to the next available row and then run the procedure. The procedure is leaving the old date and removing the new data as the duplicate. How can I modify so that it recognizes that the new pasted data are the duplicated records I want to keep and removes the old date as the duplicates?

Range("A11:T1000" & LastRow).Select

I was able to resolve by Tim Williams' suggestion to sort data in such a way that I had to get the new data above the old data. I accomplished this by using a helper column to timestamp the data.
I am not an expert (at all) so I am sure it can be written much more efficiently, but here is the full code for anyone seeking this topic:
Sub RemoveDuplicateRows()
'Demonstrates how to use the VBA RemoveDuplicates method to remove
'the duplicate rows from a particular column in a range of data.
Dim MyRange As Range
Dim LastRow As Long
ActiveSheet.Unprotect
Application.EnableEvents = False
Dim r As Range
Set r = ActiveSheet.Range("$a$10:$u$1000")
If (ActiveSheet.AutoFilterMode And ActiveSheet.FilterMode) Or ActiveSheet.FilterMode
Then
ActiveSheet.ShowAllData
End If
Range("a11:u1000").Select
Selection.Sort Key1:=Range("U11"), Order1:=xlDescending, Key2:=Range("B11") _
, Order2:=xlAscending, Header:=xlYes, OrderCustom:=1, MatchCase:= _
False, Orientation:=xlTopToBottom
LastRow = ActiveSheet.Range("B" & Rows.Count).End(xlUp).Row
Set MyRange = ActiveSheet.Range("A11:U" & LastRow)
MyRange.RemoveDuplicates Columns:=2, Header:=xlYes
Range("A11:U" & LastRow).Select
Selection.Copy
'pastes range with duplicates removed
Range("A11:U1000").Select
Selection.PasteSpecial Paste:=xlPasteFormats, Operation:=xlNone, _
SkipBlanks:=False, Transpose:=False
Application.CutCopyMode = False
Range("A11:U11").Select
Selection.Copy
'Copies formatiing
Range("A12:U1000").Select
Selection.PasteSpecial Paste:=xlPasteFormats, Operation:=xlNone, _
SkipBlanks:=False, Transpose:=False
Application.CutCopyMode = False
ActiveWindow.SmallScroll Down:=24
GoToEnd
Application.EnableEvents = True
End Sub
