Foreign Key creation in forward engineer (no replies)

I forward engineer a database and my foreign key create statement is like
CONSTRAINT `fk_Activity_Activity Source Type1`
FOREIGN KEY (`Activity_Source_Type_Identifier`)
REFERENCES `partneradb`.`Activity_Source_Type` (`Activity_Source_Type_Identifier`)
ON DELETE NO ACTION
ON UPDATE NO ACTION,

Question: where is Source Type1` coming from and what does it mean?

So it gives issues when I create Java Objects for Hibernate.
I need to have DDL syntax like
KEY `FK_ADDRESS_ID` (`ADDRESS_ID`),
KEY `FK_CONTACT_ID` (`CONTACT_ID`),
CONSTRAINT `FK_ADDRESS_ID` FOREIGN KEY (`ADDRESS_ID`) REFERENCES `address` (`ADDRESS_ID`),
CONSTRAINT `FK_CONTACT_ID` FOREIGN KEY (`CONTACT_ID`) REFERENCES `contact` (`CONTACT_ID`)
