Storage Migration Failed to add existing storage from free disks.

[INeedHelp]

Hi everyone,
new member here; I wonder if someone can help me to get back my RAID 6
Recently I bought TL-D1600S Enclosure to replace older hard drives
TL-D1600S hooked up to TL-1685 managed to back up all data; I eject correctly, then I initialise the TL-1685
and when I reconnected to get my backed data from TL-D1600S this time, it showed an error (Storage Migration [Storage & Snapshots] Failed to add existing storage from free disks. Enclosure: TL-D1600S-N778.)
all the hard disks are online, and no errors. RAID 6 and RAID 5 Online are just unable to migrate to add existing storage

here is the info
