Make repeating names stop in PDF table

I have a PDF that was created base upon a table in Word 2010.  After I turn on forms control and forms typer in Nuance Power PDF Advanced ver 1.2 I begin to enter in names. In the first column for names, when I add someone's name, as I move to the next cell in that column, if I begin to type someone else's name that has the same first letter as a previous entry in that column, a pick list will pop up to allow me to choose the name I typed in earlier. Is there a way to turn this pick list off?

Thanks,
