sliders in fixed positions on canvas

Hey guys! Merry Christmas to everyone btw! :)
Here's another noob question.
I have a 3D sketch and I added a
timeline slider using controlP5 configurations. However, it seems that the entire slider turns when I turn the camera...
How can I make it "lock" on a specific place on the canvas? What am I doin' wrong?
Here's part of the script with all arrangements for the slider marked in yellow:
import peasy.org.apache.commons.math.*; // imports all 3D related libraries
import peasy.*;
import peasy.org.apache.commons.math.geometry.*;

float worldSize = 300; // the space - rendered as a cube - limiting agents movement
StopWatchTimer sw; // a visual timer-clock implementation on canvas
int time; // a counter for time triggering events
int wait = 1000; // 1 second
Facilities work; // wondering agent -- represents (W)
Facilities retail; // wondering agent -- represents (R)
Facilities school; // wondering agent -- represents (S)
Facilities leisure; // wondering agent -- represents (L)
ArrayList <Capsule> agents;
float d = 25;
int counter=0; // counter inception
int temp=0;
boolean animate = true; // boolean for pausing the animation sequence
void setup() {
size(600,600,OPENGL);
cam = new PeasyCam(this, 300);
cam.lookAt(150, 150, 300);
cam.setMinimumDistance(10);
cam.setMaximumDistance(1500);
time = millis(); // store the current time
smooth(); // setup of visual time clock
println (millis());
sw = new StopWatchTimer();
sw.start();
// Interface Sliders
controlP5 = new ControlP5(this);
timeline_slider = controlP5.addSlider("timeline", 0, 180, 20, 550, 200, 10); // name, min, max, default, x, y, w, h
// creating the facilities
work = new Facilities(50,50,50); // generates a hypothetic invisible agent (W)
retail = new Facilities(30,30,30); // generates a hypothetic invisible agent (R)
school = new Facilities(240,240,240); // generates a hypothetic invisible agent (S)
leisure = new Facilities(90,90,90); // generates a hypothetic invisible agent (L)
agents = new ArrayList<Capsule>(); // creating the agents
// setting the emitter in random positions for each group
for (int i = 0; i < 115; i++) {
if (i < 20) agents.add(new MW1(150,150,150,color(255,0,0),i)); // Red
else if (i < 45) agents.add(new FW1(100,100,100,color(0,255,0),i)); // Green
else if (i < 65) agents.add(new MW2(200,200,200,color(0,255,255),i)); // Cyan
else if (i < 85) agents.add(new FnW2(80,80,80,color(0,155,0),i)); // dark Green
else if (i < 95) agents.add(new MW3(130,130,130,color(255,255,0),i)); // Yellow
else if (i < 105) agents.add(new FnW3(60,60,60,color(255,0,255),i)); // Purple
