I think there is a bug in the mobile version(android app) of task

there is an annoying bug in the task version(android app), 
here is the issue, lets say there is task pending witch was previously made on the computer and while on the road if someone would want to edit this already made task although the associated contact is visible on the display screen of this task when we go in edit mode, the task loses its associated contact and we have to find  the contact all over again to re-associated it to this task.
