Hi Ola.
Your case reference is 00355838 should you need to contact us directly regarding this issue.
I have also replicated this issue in ActivInspire and see that when naming the grouped objects this doesn't stay with the grouped object but however the individual items in the group.
I have passed this case on to our Escalations department to investigate this and hopefully implement a fix or a solution in the future releases of ActivInspire.
If you have any questions please do not hesitate to get in touch.
