Import from Excel does not change hierarchy of requirements (parent/child)

Hello,

we have requirements in Spira test but need to reorganize them (i.e. make some of them childs of others - we have 5 levels).

Steps we took:

1) Export requirements from Spira to Excel (after downloading the plug-in and the special sheet)

2) Reorganize (moving) rows (= cut and paste) including Increasing idents (Excel functionality at Home ribbon)

3) Import requirements back from Excel to Spira

The import runs succesfully but the issue is it does not change the positions of requirements in Spira (= no parents/child changes)

We run Spira 4 and Excel 2010

Thanks in advance for any help!
