Current operational code is no longer compiling

Troubleshooting
1

I have code that is currently operational in a Photon, is was compiled and loaded a couple months ago. I went to update the Blynk token only and re-compile, I get the following errors as listed below. I am curious if something changed in the IDE app ? Sorry in advance if this is a real simple issue. Appreciate any help from the community.
Error List:

Here is the code from a temperature/humidity/light sensor project that has been operating properly for the last couple of months:

// This #include statement was automatically added by the Particle IDE.
#include <photon_book.h>

// This #include statement was automatically added by the Particle IDE.
#include <PietteTech_DHT.h>

// This #include statement was automatically added by the Particle IDE.
#include <blynk.h>

double volts = 0.0;
int analogPin = A0;

void setup() {
   Particle.variable("analog", &reading, INT);
   Particle.variable("volts", &volts, DOUBLE);
}

void loop() {
  reading = analogRead(analogPin);
  volts = reading * 3.3 / 4096.0;
  delay(20*1000);
}

You have two sets of setup() and loop() in there.
I guess a copy/paste error
