Hi, @Bojan Zivkovic
Thank you for posting in Microsoft Q&A forum.
The query return nothing means there are no duplicate rows in the DistributionContentVersion table after you reassign a DP.
Have we queried the DistributionContentVersion table directly to see if there are no duplicate rows?
Select * from DistributionContentVersion
Have we also checked distmgr.Log for more details?
