Hello,
I hope you are doing well. This seems to be a web browser issue then I would advise you to try a different web browser.
If it does not work you can upgrade the firmware version through the console (in case is not updated)
If not we would like to take a look deeply to see what exactly is going on so you can call us to 1-866-6061866 so we can create a case for you and help you out.
Regards,
