the gyro menu is a gain controller, except instead of using endpoints to control it, you use percentages. by default, that is set to aux2. i just wanted to make sure nothing got changed, cause it that is enabled to aux3 and in the main page 15 setup menu, you have the dial set to gyro, then in gyro menu, it is set to 0%, your not gonna see a gain in the naza software. if the gyro menu isn't set to aux3, were set. if it is set to aux1 which it could be, we would want to make sure to make the bottom of the gyro menu say inhibited so it doesn't get in the way of troubleshooting it
the same could happen if the gyro menu was set to 100%, it will lock the x1 over to 100% like you mentioned and all choices would be 100% so it would appear not to work
