I'm sorry for the inconvenience, Freek!. I've forwarded this report to the development team for their review. Hopefully this is something that can replicated on our end. However, if it's necessary, we may need to get you in touch with the Support Department for a further review of your installation.
I will add updates to this thread as they are available.
Thank you,
Andrea
