The pin numbering you show is what I normally use _though it is not universal_. As a result, for an attenuator _usually_ I would have 1 at ground and 3 being the signal being attenuated, unless it’s a situation where attenuation makes some aspect of the circuit go “bigger” or “higher”. So without examining the schematic carefully I can’t be sure but RV2 and RV1 look backwards to me.

RV3 isn’t an attenuator, it’s a variable resistor. Again it depends on the circuit but very commonly you want counterclockwise to be 0R and clockwise to be the full resistance, so you either connect pin 3 to pin 2 or leave pin 3 unconnected, as in RV3.

It’s really easy to get a pot symbol backwards in a schematic and (if it’s board mounted) end up with backwards behavior.
