In our logs I’ve found a list of track files on your device. There is one recent track and some from 2015. There is no 2015-09-16, though. So, there are two com.gsapps.raceqs folders on your device.
Sometime between 2015-09-16 and 2015-09-30 Android has changed its mind on what storage to expose to the raceQs app. This could happen as a result of inserting/removing an SD and some other events.
Try to remove an SD card and then check com.gsapps.raceqs again. You may also need to reboot the phone.
Hope this helps
