Zoho - Outlook plugin

Zoho - Outlook plugin

Does anyone know if there is a way to modify the autofill in the Zoho plugin in outlook? When we create a contact, it enters the correct email address and name, but then pulls information from our own signature line to add phone number, address, etc. 
I don't want to turn off autocomplete from Outlook because it is used in outlook itself but some of my team are not deleting the field that are auto filled with our own information.
