Many duplicate lines in Aurena Graphical Org Structure - Assigned Employees Tab

We have a matrix organisation structure and have recently moved to Aurena from IEE  (Apps 10 UPD 12.)

When we look at the assigned employees tab of the Org Unit we see multiple duplicate lines of the first employee.

I scroll down and clicked “More” twice and still the first employee - so 72 rows at this point.

Has anyone seen this before?

I’ve raised a ticket but it renders this screen unusable for the HR team who have to revert to IEE.
