Ana mod wheel programming

I am having trouble getting the mod wheel to drive vibratobr
I source the mod wheel in mod 1br
target lfo 1 depthbr
turn amount up clockwisebr
I target all oscilators pitch and send a little to itbr
then I set the ratebr
the mod wheel does nothing until I dial in a little depth, and then its on all the time br
I’m sure its something obviousbr
hope that was understandablebr

On the lfo target knob turn it up very lightly maybe 1/2%br
It us very sensitive.
