Somehow i've got two running with 0% and 15% respectively, i don't remember setting these but now i gotta wait 9+hours to rerun. having a cancel button would be nice. 

This was already suggested long time ago. But I will add my thoughts here too.

Cancelling expedition should not reset its requirements or should use one of the 6 daily resets. 
Team return time after cancellation should be the same time that expedidion is already happening (sicarios has to come back) no cancellation available if 1/2 time already passed.
