User and group field values not propagating in Sharepoint 2013 variation

Hi,

I have a issue, we have a User and group field in my Content type and this content type is attach to Pages library.

I created one Page in source variation site and fill User and Group field with two user one is domain user and another is sharepoint\system account user.

After variation work and page propagate to target variation , there is only sharepoint\system account and no domain user in user and group field.

*****The main issue is domain user are not propagating in target variation site's fields.

Thanks,

dinesh
