DUPLICATED OPTIONS IN TARGET

If the options in the target appear duplicated what you should do is to comment the duplicated models. By default the script comes with the model in name and in hash, depending on the target script you use. Try to comment the hashes or names in this way in the config.lua:

PetsModels = {
    "a_c_rottweiler",
   -- -1788665315, -- a_c_rottweiler
    "a_c_husky",
  --  1318032802, -- a_c_husky
    "a_c_poodle",
  --  1125994524, -- a_c_poodle
    "a_c_retriever",
   -- 882848737, -- a_c_retriever
    "a_c_pug",
   -- 1832265812, -- a_c_pug
    "a_c_shepherd",
   -- 1126154828, -- a_c_shepherd
    "a_c_mtlion",
   -- 307287994, -- a_c_mtlion
    "a_c_shepherd",
   -- 1126154828, -- a_c_shepherd
    "a_c_westy",
