Absence once submitted shows status as awaiting approval and then suddenly goes back to saved status

We are facing an issue as soon as I apply absence and submit it the status is awaiting approval and when I go on timesheet and submit my timecard it doesn't consider by absence and when I come back to my existing absence page the status is changed to saved.So even if status is saved it is coming on timesheet but not getting submitted.

Apply absence on 30th sep for half day

Filled timecard

Automatically status is changes to saved

Now if I resubmit it then it will work
