I'm sure that was a glitch. Your GPU 0 got an incorrect share, and I'm sure the GPU 0 hasn't any share to the pool (check it) that's usually caused by OC setting (you need to lowering it)
**EDIT: In the pool only reported hashrate is anormal hi. The Current calculated and average is low. Seems that the card is near death

That's shown that only one card worked and had a valid share to the pool.
