In the schematic and layout pdf files shouldn't pins 33 and 34 be connected to ground?

nrf51x22_qfab_schematic.jpg I was going over the schematic and layout pdf files for the nrf51x22 before I began to create my own board and noticed that Pins 33 and 34 are not connected to anything. Aren't both pins supposed to be connected to ground? or is this connection unnecessary? I'm planning on connecting both to ground because the datasheet says to and doesn't say NC, but I thought I'd ask to at least point this out.

@Michael: I assume you were talking about the QFN package. Pin 33 and 34 should be connected to ground. Please take a screenshot of the layout and schematic you found that it's not connected and add to your question. Also please provide a link from where you download it.
