Thanks! The eye blinking has a few options.
Hybrid: Uses camera tracking for blinks but also auto-blinks after a set amount of time of no detected blinks.
Camera-Only: Only blinks based on your actual eye blinks.
Auto: Blinks automatically after a certain amount of time.
You might just need to change that option in the X-Y tab. Also, it helps to put your hand in front of the webcam for a second after first starting the program to help the camera recalibrate. Also helps to open your mouth wide and squish your face a bit first.
Also, for the highest quality blinks make sure you're on tracking quality 3
