The latest SKU/PURL/Bundle build 476 released on 26th February 2021 is not yet updated on US and EU clouds.
On-premise customers accessing the cab files from PLC 2.0 may have trouble updating to build #476.
There has been an issue observed that the imports are failing due to insertion of duplicates.
This issue is being looked at internally and the root cause is yet to be identified. The plan is to generate another build with the fix. We hope for this issue to be fixed soon and will continue to provide updates.
P.S - Here is the release notes of SKU, PURL & Bundle updates build 476
