FeedbackStatusUnknown from SRX's encoder

Technical Java
#1

talon4.setFeedbackDevice(FeedbackDevice.QuadEncoder);
SmartDashboard.putString(“Is there an enoder on talon4”, “” + talon4.isSensorPresent(FeedbackDevice.QuadEncoder));

This code yields the following output in the smart dashboard
“FeedbackStatusUnknown”

We do have quad encoder, we can see it from the browser in the self-test. However this feedback status unknown is puzzing. Are we doing something wrong?
