AIP Restore rejects items with a past lift date

I have migrated one of my test instances to 6.0 RC3 and I am attempting to populate my repository using exported AIP packages. Some items are being rejected due to a past lift date.

Replacing DSpace object(s) with package located at /opt/dg-transfer/data/resources/aip_10822-761364_10822-761419_10822-761857.zip

If I attempt this same action in a DSpace 5 instance, it is successful.

Beginning replacement process...
