Custom HQ "PO" Report - "Copy as Table" function

We currently have a customised report running on HQ that gives us a detailed breakdown of all PO's across our stores. The breakdown shows us both the PO Date and the PO Required Date and is in format dd/mm/yyyy. However when the report values are exported into excel using the "Copy as Table" function, both the PO date and PO required date outputs show on occasion as a date&time output in excel i.e.  dd/mm/yyyy hr:mm. Is there anyway we can restrict the RMS report values to only output to excel in dd/mm/yyyy format?

Both entries for the PO Date & PO Required Date are shown below:

Begin Column
   FieldName = "PurchaseOrder.DateCreated"
   DrillDownFieldName = ""
   DrillDownReportName = ""
   StoreIDFieldName = ""
   Title = "PO Date"
   VBDataType = vbDate
   Formula = ""
   ColHidden = False
   ColNotDisplayable = False
   FilterDisabled = False
   ColWidth = 990
   GroupMethod = groupmethodNone
   ColFormat =
   ColAlignment = flexAlignLeftCenter
End Column

Begin Column
   FieldName = "PurchaseOrder.RequiredDate"
   DrillDownFieldName = ""
   DrillDownReportName = ""
   StoreIDFieldName = ""
   Title = "Req'd Date"
   VBDataType = vbDate
   Formula = ""
   ColHidden = False
   ColNotDisplayable = False
   FilterDisabled = False
   ColWidth = 1050
   GroupMethod = groupmethodNone
   ColFormat = ""
   ColAlignment = flexAlignLeftCenter
End Column
