Rounding Adjustment Not Working

For the payment linked below the rounding adjustment was not working. The rounding adjustment showed zero no matter what I did. I had to apply $0.01 to Unapplied Cash in order for it to work.

The payment value is $24,509.95 and the Raw Applied Total was $24,509.9356 prior to me applying the 0.01 to unapplied cash the.

Thanks
