Leave/OT request entry - "from" and "to" hours field does not carry over after approval

When entering a request for leave/OT, employees enter the leave/OT time frame (i.e. 7am to 9am) in the "From-To Hours" field to detail the hours of day they will be absent or worked OT. For example, an employee would enter "7am to 9am" to evidence the hours worked when requesting OT on a Saturday.

When the supervisor approves the leave/OT request, the "From" and "To" time fields blank out as the entry does not roll over to the approved time request. For example, the "From" field and "To" field on the approved leave/OT request is completely blank as the employee entered "7am to 9am" does not carryover.

I am requesting the employee entered "From-To Hours" information populate in the supervisor approved request in order for this valuable detail to show on the employee timecard. Evidencing the actual time frame the employee is requesting off/worked OT is valuable information and needs to roll over to the approved leave/OT request.
