The output seems a little strange and I'm not sure why that is.

Output should be
   ALPHA |   OMEGA |   GAMMA | EPSILON |   GREEK |    BETA
       1 |       2 |       3 |         |         |
       4 |       5 |       6 |    10   |      11 |       15
         |       9 |         |      7  |       8 |        0
         |      13 |         |      12 |         |

instead it gets:
   ALPHA |   OMEGA |   GAMMA | EPSILON |   GREEK |    BETA
       1 |       2 |       3 |       7 |       8 |       0
       4 |       5 |       6 |      12 |      11 |      15
         |       9 |         |      10 |         |
         |      13 |         |         |         |

Please advise on what's going on.

Thanks
