Problem description
Trips page: New trips creation: Calendar service dropdown:

The information next to the service_id is given for the user to figure out which days of the week this service is operational, and in what time period. Here, it says all the service_ids are operational on all the days of the week.
But in Calendar page, the service_ids are clearly having different days of week flags.

Expected Action
WK should be "MTWTF" only.
SU should be "S" only
SA should be another "S" only.
