Sending an Uber for someone else; app keeps switching to MY location (see details)?

I'm currently on vacation in Nevada, but my girlfriend is back home in Houston. I was trying to send her an Uber, so I entered her location and scheduled the ride, but I couldn't check up on the status of the ride, because the app kept defaulting back to my location in Vegas. So I dropped a pin at her location and her driver's info popped up, but then in just a couple of seconds it automatically forced me back to my location again.

I tried this several more times, and every time I checked up on her location the app forced me back to the Vegas location, not even giving me enough time to do anything

Eventually I acted fast enough to go to "call driver" before it swutched again so I was able to speak to him and confirm the details, but why couldn't I just do it the normal way through the app? Why did it keep forcing me back to my own map location?
