When I specify the RX or RY gate to rotate by say $\pi/4$ in the circuit composer, the gate disappears off the circuit. Is there any reason why if I leave it with $\pi/2$ default then it stays?
If I edit theta the gate disappears.
Here's some screenshots to show what happens:
Ok solution is to erase the whole field $\pi/2$ and reenter $\pi/4$ but leaving $\pi/$ and then denominator $4$ will not work. Also the denominator is bounded between 1 and 9.
