Teensy 3.6 Encoder Pin sensitivity issue.

Hello,
I have programmed Teensy 3.6 for driving stepper drives using hand wheels encoder.
But It was worked a while. Pin sensitivity or noise issue making the trouble.
After sometimes it start generating noise and motor run by itself. I have checked the encoder self counting when other stepper drive power on. But if I disconnect the hand wheel encoders noise stopped. when encoder disconnected self counting stop. But, when moving disconnected encoder cables from the teensy board, it count again. when I start a dc motor not even conected to same circuit same story.
Is there any suggestion to get rid of the sensitivity issue?
Kind Regards

Hi,
I have solved the sensitivity issue with using these simple filter circuit with 4 piece 10 k resistor without capacitor.
