Management Group ID Error - Upgrade to Terraform 2.20

When updating to Terraform 2.20 of the Azure provider, we are seeing in the plan phase: Error: Unable to parse Management Group ID “/providers/Microsoft.Management/ManagementGroups/XXXXX-MG”

When I browse the state I still see: management_group_id = “XXXXX-MG”

The upgrade changed management_group_id to management_group_name in the Azure provider, so is this just an error from the plan stage since it is reading the old state? The plan shows no changes and seems to complete, so will this error go away once we apply?
