Posting back to Core HR for part time employees is inaccurate

Summary

The post back to core HR from WFC for part time employees is not taking into consideration the employee's FTE.

I feel like I am missing something here. The requirement seems so simple. 

Client has part time employees with FTE that is below 1. We are merit planning for them and want to post back to Core HR from WFC. When we post back part time employees with less than 1 FTE, it is not posting the correct amount.

Example:

Employee has an current base salary of 23.93 (hourly) with an FTE of .6

So adjusted salary - current is 14.36

Eligible salary is a prorated amount based off their adjusted salary. This amount happens to be 8.61 for the example.
