Issue with shared member in metadata load using file

Content

All,

I am facing issue to load shared members to the Account dimension during metadata load using flat file. I am not sure if there had been changes to required fields to load metadata using files or I am missing out anything. 

File includes following columns with pipe (|) as delimiter

Account|Parent|Alias: Default|UDA|Data Storage (<ASOcube>)|Time Balance

I am populating the base members before the shared members in the file but when loading the file, receive following error. This happens when this shared members does not exist in the hierarchy and newly added via file. If the shared member already exists and file is attempting to load it, it goes through correctly. The Parents for both base member and shared member are unique, not sure why it is attempting to change the base members' property.
