What does it mean if it says “shift preference was submitted “ mean?

I put I can do 4 days when I suppose to put 2 since they’re looking for that for Amazon sortation. I emailed them and they said that “shift preference was submitted successfully” now I originally chosen the days back in June 26th but after the email it said it was submitted so does it mean it’s under review and did they change it? Maybe not I’m not sure 🙄
