Pneumatics Piston not working in python

[FRC Fanatic]

Hello, so i'm trying to understand how to program pneumatics in python in the off-season. I've read the Robotpy documentation and the Pacgoat pneumatic documentation on github and i want to make sure that the issue is not code side, because the kFoward is functional but not the kReverse

here is a quick rundown of the pneumatic setup
double solenoid on Vex Manifold is running to 1 piston which we just want to control.

here is the code as follows

#!/usr/mybin/env python3
import math
import wpilib
from RobotMap import RobotMap
from networktables import NetworkTable
from wpilib.doublesolenoid import DoubleSolenoid
class MyRobot(wpilib.IterativeRobot):    
    def robotInit(self):
        self.xb = wpilib.Joystick(2)
        
        self.Compressor = wpilib.Compressor(0)
        self.Compressor.setClosedLoopControl(True)
        self.enabled = self.Compressor.enabled()
        self.PSV = self.Compressor.getPressureSwitchValue()
        self.DS = wpilib.DoubleSolenoid(1,2)
        self.Compressor.start()
 def teleopPeriodic(self):
        elif(self.xb.getRawButton(2)):
                self.DS.set(DoubleSolenoid.Value.kForward)
       elif(self.xb.getRawButton(4)):
                self.DS.set(DoubleSolenoid.Value.kReverse)

is there any glaring issues? i'm new to pneumatic programming and any assistance would be great, thank you.
