What's probably wrong is that hf_wca_label_2_number probably doesn't have one of the types required by 
proto_tree_add_int():

If it's not one of those four types, and you're using proto_tree_add_int(), that's an error.

If it's an unsigned value, then

        1) its type must be one of FT_UINT8, FT_UINT16, FT_UINT24, or FT_UINT32

and

        2) you must use proto_tree_add_uint(), not proto_tree_add_int().
