Track rod ends

Had my 1000 mile bolt check completed & everything was fine apart from the tracking which they adjusted & there was a noticeable improvement (ive only done 400 miles in it lol the project manager had completed the other 600...).

Had a quick look at the front suspension when I got back & one trakrod end has a lot of thread showing & the other one has none? Can this be right? I would have thought they would be identical? I know they started off as identical when I put it together as I had to take the suspension apart to do this...
