Piotroski Score calculation for HUN is off in 2015

Hi, I noted while checking one of my investment, that HUN is off in its 2015 net income quality check for piotroski score. 

System shows a check for increase in NI for HUN between 2014 and 2015. But, 2014 was at 345M and 2015 was only 126M. So it should be 0 rather than 1. 

Possible to take a look as it may affect other stock's historical scores as well.
