Article indication is basically an obedience exercise. I would go back to working the articles off the track. Ensure the dog has a solid, down stay. Lay a track about 15 yards long and place articles every 3 yards or so. Bring the dog up, keep the leash short and proceed to each article. When the dog gets to the article, command Platz and enforce if the dog doesn't down immediately. Pay between the dogs legs, dropping the food between it's legs. Before, you move on to the next article, cover the dog's eyes with one hand and toss a piece of food a foot in front of the dog. This way the food appears after the dog has indicated on the article, there is no odor to pull the dog past the article. When you do this, it is like a "slight of hand" trick. You cover the eyes, so the dog doesn't see you toss the food. Praise, calmly and restart the dog. This also corrects any dogs that "jack rabbit" start after the articles. Dogs that bounce up and want to fly down the track. It causes the dog to start slowly and check for footprints right after the article.
I am assuming that you have already taught the articles with food either on the article or just in front of it.
After you back up in tracking training with the articles, go back to adding them on the track. It is very important to know exactly where on the track the articles are before the dog gets to them. You may need to stop the dog at the article and give the platz command. Make sure the dog downs, correctly and praise and reward. After the indication, cover the eyes, toss a piece of food a foot in front of the dog and restart.
See if this helps?
