payout ratio bug in screener

I have tried repeatedly to set the high end of payout ratio threshold to 50%. The screener changes the input to 0.5% which is clearly not the same thing. No matter what I have tried, the screener will not allow me to set a proper payout ratio. The slider only jumps in 100% increments. There also seems to be some bugs in the data showin some companies paying a dividend with a 0% payout ratio.
