They should do something, but it is "subtle".

1) With nothing connected to the inputs, Offset should be able to trim the
output to 0V.
2)With a CV being fed it, CV Rej should be able to trim any offset at the
output to 0V.

Has to be done in that order.

If you need more gain, increase the two 130k resistors in the output stage
to 270k. That will double the output level.
