Fluid Enrollment Swap Classes - Save Option

If a student chooses the Swap Classes activity guide. Then they click on another activity guide (say, Drop Classes) they are presented with "Do you want to save your changes? Click Yes to go back and save, No to discard your changes." If they click the Yes button they return to this page but when they do there is no obvious ability to save.  Am I missing something? It is also a little bit strange to even offer the ability to save the Swap Classes information.
