Thank you all for taking the time to respond. I think her alerting issues are mainly because of handler errors in training. I was sometimes rewarding the eye contact because I was taking it as a cue from her that she found the hide, but she seems to do better when I am not rewarding her for that but instead rewarding her for having her nose on the hide and giving her jackpots of treats when she's doing a down with nose on the hide. I am now being more careful to time the rewards accurately. Also did the blind hide thing. She's already doing much better and using her nose more since I stopped rewarding the eye contact and instead rewarding a lot for focus on the hide. No false alerts today.
