On BoxRec's list of International Boxing Association titles, "No Data Found" appears when one clicks on the flyweight class.
There has been at least one IBA flyweight title bout. On April 17, 2007, Isidro Garcia outpointed Cesar Lopez to win the vacant IBA title. That bout appears on both fighters' records with the notion that it was for the IBA flyweight title.
The information in the "titles" section should be updated.
