Balance from vacation plan transferred to sick plan upon loss of eligibility

Hi Team,

I was doing some tests on balance transfer once employee loses eligibility on certain absence plans. The scenario was:

Employee with Assignment Category: Casual-Full

Enrolled to the following plans:

• Vacation Leave-Monthly Accrual
• Sick Leave

Change on Assignment Category from Casual-Full to Casual, effective September 26.

Enrolled to the following plan:

• Sick Leave-Casual

Result:

Employee's eligibility to previous absence and sick plans got end-dated effective September 26 and the balances from those two plans were all transferred to Sick Leave-Casual.

Is that the expected behavior if the balance from the old vacation plan have nowhere to transfer to and so it was transferred to the sick plan?
