Thank you for the circuit. I tried to replicate it but unable to get the result that you are getting.

But the duty cycle is still not fixed as you have(50%)

Look at the signal on the output of the logic gate. I don't like the name you have. I suspect that your logic gate has a 6V supply as a result the thresholds do not correspond to 5V.
