Vencillio source Help
This seems like a client issue, possibly related to read values. You need to change them to match the data you’ve packed.
Unless you changed the bits for your client, there’s nothing server sided you need to change directly (You might need to update some definitions for the server to know what npc is what though).
As X-J-K-X said, it should be client sided, make sure you have both the npc models and configuration packed into the client. And on top of that - you have the correct read values
