Lookup field conversion issue from Leads to Accounts and Contacts

Lookup field conversion issue from Leads to Accounts and Contacts

Hi

I have created a module called "School Assocation" in Zoho CRM. I created a lookup field in Lead for this module.

I also created a similar lookup field to the same module (School Association) in Accounts and Deals. 

When I go to "Lead Conversion Mapping", I am able to map this field in Deals but it is not showing in the Accounts mapping. For some reason, the mapping is there only for Deals. Why am I able to map the lookup only for Deals and not for Accounts?
