Double booking and after hour support

Being able to pick up 16 hour shifts at two different facilities for the same day. I've experienced this twice now working with nursa. I am unable to request through the app because the start and end time are the same. So I've had to have the facilities call nursa and put it in manually.  I try to work 16 hours day and it doesn't always work out at the same facility due to thier needs, so I would see another facility needs help at the time my shift ends and I have to call the facility directly to ask if I can work, since I can't put a request in. 

#2  After hours when you call they ask if this is an emergency press #. When you do, it brings you back to the main menu, there doesn't seem to be an after hours way to contact Nursa.
