Thank you for providing us with the requested screenshot!
Hmm, indeed it is rather odd as we have never encountered this before.
Could you kindly perform a wipe cache partition of your device?
This is done by turning off the device, pressing and holding the volume up button + power button at the same time, once the recovery menu appears, select "Wipe Cache Partition" (Navigate by using the volume keys and power button to select)
Note: Please make sure to select Wipe cache partition, and not Wipe data/factory reset - the latter will erase all data on the internal storage of the device.
Additionally, were you able to figure if this was caused by any third party application you recently installed?
Looking forward to your answer!
Its been sorted Max I told her it might have been an app, I was correct it was to do with a ringtone app
