Imported data from backup has the new created objectId for each item

I made backup of User data, deleted table values, and after import i see that all items have the different objectId. So after import i lost link User -> Another Table by ownerId, because it has been changed !
Why importing , objectId is changes ? How can change now manually objectId of each User ?

Hello, Aleks!
I’ve created an internal ticket “BKNDLSS-13370” to investigate this issue.

We shall notify you in this thread about results.
ObjectIds cannot be set manually. It looks like a bug on our side.
Thank you for reporting.

ok thanks
