I’d reduce that down to something in the nF to 1uF range. Post as a guest Name. Also, have you added a 0.
4-bit Synchronous Counter with Asynchronous Clear
That’s probably causing as much trouble as no debounce was. I switched eheet LEDs around and connected their input to 5V and their ground to the output pins.
Without this buffering, your switch should not work on a button push, only on a release. For a circuit board with a ground plane, the usual guideline is at least one cap per 5 ICs. Sign up using Facebook.
It’s always the simple things. Email Required, but never shown.
Then I used a pullup resistor for the clear switch. Oh, Ill change that and see what happens. So your outputs should be connected like. Sign up using Email and Password.
Finally, you should not count on TTL outputs driving high, as you have shown. You may object that this will provide LEDs which are on when the output is low, and off when the outputs are high, which is confusing.

For breadboards, use a cap for each IC. I’m still getting the same effect.
You can often get away with less, but as you’ve just learned, insufficient decoupling can have weird symptoms. I have added a debounce circuit, but still to avail. Get into the habit now. 7416 your outputs should be connected like simulate this circuit — Schematic created using CircuitLab You may object that this will provide LEDs which are on when the output is low, and off when the outputs are high, which is confusing.
I added a 0.
