The 1M resistor between the oscillator and counter is not required and might stop the circuit from working because it will combine with stray capacitance between wires and cause the square-wave from the oscillator to be a triangle-wave at the clock input of the counter. If only one input is used and the spare input is connected to the positive supply voltage then the output will be more symmetrical.

The wave is not exactly square in shape. Your simulation software is wrong because it shows the input going 4V higher than the positive supply and 4V below ground.
