We are unable to integrate Zoho MA with Zoho CRM due to an error message being displayed

We are using the Zoho One version and would like to integrate both tools. However, during the integration process, an error message appears stating 'This account is already integrated,' although we do not have Zoho CRM integrated with Marketing Automation. We believe this might be an issue. Could you please assist us in resolving it?
