Hey, there are several possible explinations:

1, Did you edit an existing NPC entry or add your own?

If you added your own struct, you need to set the struct ID to 4.

2, Your .git file is corrupted. Try using the K-GFF Editor by tk102, if this is the program you are already using, corruption is most likely not the issue.

3, You've got your tags and resrefs wrong.

Oh and about Z co-ordinates, it doesn't really matter, your PC is automatically "snapped" onto the walkmesh.
