SSM10 - Select multiple filters in Scorecard defaults

Hello,

We have the following problem: We cannot select more than one hierarchy level from the dimensions in the Context management - Manage scorecards - Scorecard defaults menu:

What are we doing wrong? The Add All Members button is inactive..

We are using the last version - SP 5 HF 3, on netweaver as java 7.3 ehp  1.

Thanks,

Andreea D.
