New Zoho Support UI - Duplicate email issue

New Zoho Support UI - Duplicate email issue

We just started using the new Zoho Support UI, looks great however. 

We use to be able to submit tickets on the clients behalf an use our agents email address but now with the new UI update we get the following:

Duplicate Contacts with the same email address exist, Please choose the appropriate and proceed

The only reason we did this was to avoid sending out change requests to our clients when the request was submitted by the Agent. And we also have on the support notification emails so instead of the system alerting the client it would keep the agent who submitted the request informed.

Please advise and thank you,

Thomas
