After changing my primary email for Apple ID, iCloud has issues

I recently changed my apple ID primary email address as the old email address is not obsolete which meant I had to turn off iCloud on all devices and log back in so that the username/email was correct for password verification. Now that I have done this, iCal has 7 calendars, reminders has about 4-5 reminders lists and contacts has about 500+ blank contacts.

When I go to delete these extra calendars, reminders and contacts. They delete but within a few seconds they reappear. I've rebooted, I've tried deleting them through icloud.com and also directly from each device. I have 3 devices using icloud. I have turned off 2 of them at a time and tried deleting from the remaining device.

Has anyone got a solution please?!!?? Starting to get frustrating.
