Inertial Sensor is acting weird

so i am trying to turn using the inertial sensor’s heading block in block code so it is accurate. However, the sensor returns a value from 100-999, which i don’t think is possible since vex documentation says this**The Angle of Heading block reports a range from 0.0 to 359.99 degrees. How do i fix this problem. And to people who would tell me to factory reset the sensor, how do i do it?
