BSI Display Log Question

We are trying to research a problem with a PR80 calculation, and we are trying to figure out if this is a deduction issue or a BSI issue. When we look at the BSI log, it appears that there is an Input section, an Output section, then another Input section and another Output section.

Can someone explain what the first Input/Output is and what the second Input/Output is?

I know just enough about Payroll to be dangerous, but it appears that everything is right in the first Input/Output section, but then it gets screwed up in (or before) the second Input/Output section.

I appreciate any help you can give me.

Thanks! Kelly
