msproject strange import issue

 

I have a strange issue with msproject.

When I import from excel. The first time it is going oke, but when I add some in the project and import again, then msproject doest level right 1 beneath the inserted  row of mine.

 

Example:

 

import 1 ==> oke

Task1

- item 1

- item 2

Task2 

- item 1

- item 2

Task3

- item 1

- item 2

 

witout inserting an extra item in ms project, and import again from the same file, with merge. ==> oke

But when I do this:

 

Task2 

- item 1

- item 2

- item 3 >>>> this I insert in msproject.

 

When import and merge again, i get this.

 

Task1

- item 1

- item 2

Task2 

- item 1

- item 2

- item 3

 

what is happening ??
