Deleted Table View Cell Copying Remaining Tableview Cell Instead of Disappearing

I've got a UITableView that pulls some information from a Firebase Realtime Database. The information all gets pulled and populated properly, and deletes when it is supposed to, but I get a weird bug. If there are multiple cells in the table view, when I delete one of the cells, instead of that cell disappearing, it just gets replaced with a copy of one of the remaining cells. When I then close the table view and reopen it, everything is correct (i.e. the copied cell is gone). Here is the swift file for the table view:

import Firebase
import FirebaseAuth

class SpotRemove: ViewController, UITableViewDelegate, UITableViewDataSource {

    
    @IBOutlet weak var tblSpots: UITableView!
    
    var spotsList = [ArtistModel]()
    
    public func tableView(_ tableView: UITableView, numberOfRowsInSection section: Int) -> Int {
        return spotsList.count
    }
    
    public func tableView(_ tableView: UITableView, cellForRowAt indexPath: IndexPath) -> UITableViewCell {
        let cell = tableView.dequeueReusableCell(withIdentifier: "cell", for: indexPath) as! ViewControllerTableViewCell
        
        let spot: ArtistModel
        
        spot = spotsList[indexPath.row]
        
        cell.lblName.text = spot.type
        cell.lblGenre.text = spot.avail
        cell.lblPrice.text = spot.price
        
        return cell
    }
    
    var refSpots: DatabaseReference?
    
    override func viewDidLoad() {
        super.viewDidLoad()
        tblSpots.allowsMultipleSelectionDuringEditing = true
        refSpots = Database.database().reference().child("Spots")
        refSpots?.observe(.value, with: { (snapshot) in
            if snapshot.childrenCount>0{
                for spots in snapshot.children.allObjects as![DataSnapshot]{
                    let spotKey = spots.key
                    let spotObject = spots.value as? [String: AnyObject]
                    let spotType = spotObject?["Type"]
                    let spotAvail = spotObject?["Availability"]
                    let spotPrice = spotObject?["Price"]
                    let spotID = spotObject?["UserID"]
                    
                    
                    let spot = ArtistModel(id: spotID as! String?, avail: spotAvail as! String?, type: spotType as! String?, price: spotPrice as! String?, key: spotKey as! String?)
                    let userID = Auth.auth().currentUser?.uid
                    if userID == spotID as? String {
                    self.spotsList.append(spot)
                    }
                }
                self.tblSpots.reloadData()
            }
        })
    }
    func tableView(_ tableView: UITableView, canEditRowAt indexPath: IndexPath) -> Bool {
        return true
    }
    func tableView(_ tableView: UITableView, commit editingStyle: UITableViewCell.EditingStyle, forRowAt indexPath: IndexPath) {
        
        let spot = self.spotsList[indexPath.row]
        
        if let spotKey = spot.key {
            Database.database().reference().child("Spots").child(spotKey).removeValue { (error, ref) in
                if error != nil {
                    print("Failed to delete message:", error!)
                    return
                }
                self.spotsList.remove(at: indexPath.row)
                self.tblSpots.deleteRows(at: [indexPath], with: .automatic)
                self.tblSpots.reloadData()
            }
            tblSpots.reloadData()
        }
        
    }
