Why is every parameter of my "Services" Object working but this one?

I am creating an Array List differentServices composed of objects Services I am creating.

When I'm trying to get data from a file which would serve as services with parameters service name, service file name, and service fee and while printing the values of my array list differentService I note that the name of the services in my arraylist are all different and according to the file, the service fees of the different objects in the arraylist are all different and according to the file too, but the filename of every object in differentServices is the same even though the way I declare the new Services() is the same as for service name and service fee.

I'm trying to understand why as I need the data of every service to be different.

Here is the configuration file:

 service=Instacart,instacart.csv,5.99
 service=Prime,amazon.csv,4.00
 service=Safeway,safeway.csv,3.99
 service=GoogleDelivery,google.csv,6.99
 service=Basket,basket.csv,2.50

And here is my Service.java file:

public class Services {

   public String name = "";
   public static String fileName = "";
   public double usageFee = 0;

   //constructor
   public Services(String name, String fileName, double usageFee) {
	    this.name = name;
	    this.fileName = fileName;
	    this.usageFee = usageFee;
    }   
}
