Retention days parameter in the dest account not working as expected

[rue-witte]

Hello,
I have setup the snapshot tool for both Aurora postgres and Aurora Mysql and for both of them I set the retentionDays to 3 in the destination account. The source account has the retention of 1 day.

I only see one snapshot in the destination account/region. I am not sure why it is deleting the other snapshots when we specified the 3 day retention in the destination. Can you please let me know If something else needs to be done.
