hibernate - Hibernate giving Repeated Column in mapping for entitiy .... but it doesn't look like there is a duplicate

Question

I have project which is currently failing to deploy successfully. During deployment I get the following exception

Caused by: javax.persistence.PersistenceException: org.hibernate.MappingException: Repeated column in mapping for entity: com.bedbath.amsSched.model.AgreementVendor column: AGRMTID (should be mapped with insert="false" update="false")

I don't however see any duplicate coloumn. I have read some other posts and have tried adding insertable=false, updatable=false on the AGRMTID coloum as suggested, but it did not work.

Here is the entity class

package com.bedbath.amsSched.model;
