Can you post the TinyCAD file for that one?

I suspect the counter is coming up with odd outputs, there is no reset with the circuit. I'd tempted to connect a .1 uf cap to the supply and reset, and a 10K resistor from the same junction to ground. That would give you a power-on reset. I think if you left it run for a spell, that would all work itself out.

Don't know why you'd need the 100k.
