>From page 38 of the gmpl.pdf -- "As a rule the model description contains only one objective statement that defi nes the objective function used in the problem instance. However, it is allowed to declare arbitrary number of objectives, in which case the actual objective function is the fi rst objective encountered in the model description. Other objectives are also included in the problem instance, but they do not aff ect the objective function"
This is consistent with the behavior you've observed.
