This error happens in  SYSTEM ARCHITECT ESSENTIALS Version:8 actually.

In which exercise does this error occur?

And is this in a vm or a cloud-based exercise system?

Thank you for bringing this to our attention.  We have not been able to recreate the issue.  To help us investigate this further it would be very helpful if someone could reply with the exact steps that lead to the error.  It would also be helpful to look at the exact system where the issue is occurring, please do not post this here but instead email the URL of your Exercise system log in page and include the steps to recreate the problem.
