Each gate signal lasts a full clock cycle so it is no wonder you get a
constant 5 volts when all are used.
You need to shorten the output pulses.
Try cutting the inhibit in to the gate 4051 (pin 6 )and connecting it to the
clock instead (pin 7 of the quad op-amp).
Alternatively,
Try putting a 100n between each gate output and its switch, and a 100k from
the switch to to ground (if needed).
