D365FO Database sync failed duplicate key on ProjHierarchySorting table

While taking my one server data to other, I faced the following error on Synchronization of database:

"Database execution failed: The CREATE UNIQUE INDEX statement terminated because a duplicate key was found for the object name 'dbo.PROJHIERARCHYSORTING' and the index name 'I_19940NODEREFERENCE'. The duplicate key value is (5637144576, usmf, 0, , 0)."

I opened Sql server and found there were 22 records with many level columns having 0 value. I took backup of table data and deleted all the records with delete query.

Then I ran DB sync again from VS and it ran successfully.
