Bug in CRS enlistment?

Somebody told me about this bug in the CRS enlistment.

Description/Repro steps:

1. Student is able to preenlist after the last preenlistment batch run and before the realtime enlistment.
2. The student gets a status of Pending for that subject.
3. The Pending status remains even after realtime enlistment (i.e., walang nangyayari sa pagkapending) .

Proposed Resolution:

1. Clear all Pending statuses after the last batch run and before the realtime.
2. Prevent the student from preenlisting/enlisting during the said period.
