How to preserve the original indexPath.row after applying filters to Table View?

My app uses "filter" buttons in which the whereField query is refined based on which filter buttons are pressed. This is an example before filtering:

But this is an example after filtering:

The issue is that when I click into one of the Rows, it takes me to the next page that corresponds to the original indexPath.row in my database belonging to that Row. How can I preserve the original indexPath.row? E.g., Cell B to always be indexPath.row = 1, even after filtering.

This is my cellForRowAt of my first View Controller.

    func tableView(_ tableView: UITableView, cellForRowAt indexPath: IndexPath) -> UITableViewCell {
        
        // Get a cell
        let cell = tableView.dequeueReusableCell(withIdentifier: "MealPlanCell", for: indexPath) as! MealPlanCell
        
        // Get the mealPlan that the tableView is asking about
        let mealPlanInTable = mealPlan[indexPath.row]
        
        // Customize the cell
        cell.displayMealPlan(mealPlanInTable)
        
        // Return the cell
        return cell
        
    }

And how I connect this View Controller's indexPath.row to the next View Controller after a cell is tapped:

override func prepare(for segue: UIStoryboardSegue, sender: Any?) {
        
        // Detect the indexPath the user selected
        let indexPath = tableView.indexPathForSelectedRow
        
        // Get the mealPlan the user selected
        let mealPlanSelected = mealPlan[indexPath!.row]
        
        // Get a reference to the NextiewController
        let NextVC = segue.destination as! NextViewController
        
        // Get a reference to the currentMealPlanIndex in the NextViewController
        NextVC.currentMealPlanIndex = indexPath!.row
        
    }

Any advice is much appreciated!

Thank you all for the comments/advice! Instead of connecting the data in the view controllers through the indexPath, I used a document ID that is consistent with the data flowing between my view controllers. This works with all of my filtering.

This is in my first ViewController:

override func prepare(for segue: UIStoryboardSegue, sender: Any?) {
        
        if let indexPath = tableView.indexPathForSelectedRow {
            
            let ingredientsVC = segue.destination as! IngredientsViewController
            let documentID = mealPlan[indexPath.row].docID
            ingredientsVC.currentMealPlanIndex = indexPath.row
            ingredientsVC.passedDocID = documentID!
        }
    }

And this is in my second ViewController:

// This variable references the unique Document ID
var passedDocID = ""

// This is how I use that document ID to get a reference to the appropriate data
let selectedMealPlanIndex = mealPlan.firstIndex(where: {$0.docID == passedDocID})
            let currentMealPlan = mealPlan[selectedMealPlanIndex!]
