Can we remove an integration and if so, how? Marketing Hub will not connect to Zoho Crm

I have Zoho One paid subscription and I am trying to integrate the Marketing Hub with the CRM. When I try to sync it says my organization is already integrated but it is not. Through searching this issue it is because Campaigns is already integrated and they can not be on together. In Zoho support forum they have told people to remove the integrations(please see link). I do not understand but the link shows exactly what my problem is. Thank you

Looking now will get back to you @drjewell
