Fixed version (ground truth):

    if (cfg.getConfig("String_Node_Str"))     tip.add(StatCollector.translateToLocal("String_Node_Str") + "String_Node_Str" + Utilities.round(horse.getEntityAttribute(SharedMonsterAttributes.movementSpeed).getAttributeValue(),4));
  }
 else   if (cfg.getConfig(showProfession)) {
    String profession="String_Node_Str";
    if (FMLCommonHandler.instance().getSide().equals(Side.CLIENT) && entity instanceof EntityVillager) {
      EntityVillager villager=(EntityVillager)entity;

    }
