"invalid category" warning when using MODIS12Q1 landuse data

hi,I used MCD12Q1 to creat binary land use data,but after I run geogrid.exe,warning appears as follows:
WARNING: In /data/backu/local/geog/MODIS12Q1/index, unrecognized option in entry 14.

I also upload my binary data and GEOGRID.TBL.
Hope someone could help me check what's wrong.
Thanks a lot!
