Generated JDG modul have required in annotation for each of getters

When I deploy dynamic VDB, server shows error that:

 org.teiid.core.TeiidException: Required field must not be null : subtitle

I noticed that generated JDG class have all getters to required but in the model have set nullable to 'no_nulls' only one column(screenshot). Source db contains some row which have subtitle columns set to null. In the attachment is the project.
