title: Text in cell repeats or doubles, why?
body: <p>I typed in <code>=NOW()</code> and the cell displayed "1/6/20161/6/2016".</p>
  
  <p>Checked cell format and conditional formatting and nothing seems amiss. What can cause this?</p>
  
  <p>edit: as shown in the image below, I cannot recreate the anomaly outside of this column.  Whether I copy/paste or type in <code>=NOW()</code> the result is the same.
