"Hello Zee, Thank you for contacting Cisco Meraki support. This issue has already been reported by support to our development team. It is only affecting the dashboard output of switch aggregate ports, not the function of those ports. If you need to make changes to any ports that fail to load, please use Switch > Switch Ports or API to change them. I will notify you through this case when a fix for this issue has been pushed to dashboard. Please let me know if you have additional questions.
