CoreData saving but not changing on additional button clicks

I have an app Im trying to build with sleep data for sleep apnea. I successfully setup CoreData with some help and its saving the first user input from the textfields and displaying it in the log from CoreData (changing the strings to Doubles was a challenge but success). However, whenever I put another 2nd input in, it saves and displays the first input again. It won't change. What am I doing wrong? A side note, it also is not creating a unique ID for each entry for some reason. Thank you guys....you'd been awesome so far helping as Im a newbie.

SleepModel.swift

struct SleepModel: Identifiable, Hashable {
        var id = UUID().uuidString // ID variable
        var hoursSlept: Double // Hours slept variable
        var ahiReading: Double // AHI variable
}

Save function in AddEntryView.swift which is called when the button is pushed

 private func saveSleepModel() {
        guard let hoursSleptDouble = Double(hoursSleptString) else {
            print("hours slept is invalid")
            return
        }
        guard let ahiReadingDouble = Double(ahiReadingString) else {
            print("ahi reading is invalid")
            return
        }
        
        // Creates Sleep Model for user input & sends parameters
        var sleepModel =  SleepModel(hoursSlept: hoursSleptDouble, ahiReading: ahiReadingDouble)
        coreDataViewModel.saveRecord(sleepModel: sleepModel) {
            print("Success")
        }
    }

CoreDataViewModel

import SwiftUI
import CoreData

class CoreDataViewModel: ObservableObject {
    
     
    let container: NSPersistentContainer
    @Published var savedRecords: [SleepEntity] = []
    init() {
        container = NSPersistentContainer(name: "SleepContainer")
        container.loadPersistentStores { description, error in
            if let error = error {
                print("Error loading contaienr - \(error.localizedDescription)")
            } else {
                print("Core data loaded successfully")
            }
        }
     fetchRecords()
    }

    
    func saveRecord(sleepModel: SleepModel, onSuccess: @escaping() -> Void) {
        let newRecord = SleepEntity(context: container.viewContext)
        newRecord.hoursSlept = sleepModel.hoursSlept
        newRecord.ahiReading = sleepModel.ahiReading
        saveData(onSuccess: onSuccess)
    }
  
    func saveData(onSuccess: @escaping() -> Void) {
        do {
            try container.viewContext.save()
            fetchRecords()

            onSuccess()
        } catch let error {
            print("Error saving items: \(error)")
        }
    }
    func fetchRecords() {
            let request = NSFetchRequest<SleepEntity>(entityName: "SleepEntity")
            request.sortDescriptors = [
                   NSSortDescriptor(keyPath: \SleepEntity.id, ascending: false)
               ]

            do {
                savedRecords = try container.viewContext.fetch(request)
            } catch let error  {
                print("Error fetching requests - \(error.localizedDescription)")
            }
        }
    
}
