When isEditing is true, my texts are not aligned as seen in the picture. What is the reason?

Important : Tableview constraints codes are in a separate file.

Edit Button Code

    @objc func didTapEdit(){
    if plansListTableView.isEditing {
        plansListTableView.isEditing = false
    }
    else {
        plansListTableView.isEditing = true
        
    }
}

Constraints Code

    private func addConstraints(){
    addSubview(planLabel)
        NSLayoutConstraint.activate([
            planLabel.centerYAnchor.constraint(equalTo: centerYAnchor),
            planLabel.leadingAnchor.constraint(equalTo: safeAreaLayoutGuide.leadingAnchor, constant: 20)
        ])
}

>Solution :

Add the label to contentView

private func addConstraints(){
    contentView.addSubview(planLabel)
    NSLayoutConstraint.activate([
        planLabel.centerYAnchor.constraint(equalTo: contentView.centerYAnchor),
        planLabel.leadingAnchor.constraint(equalTo: contentView.leadingAnchor, constant: 20)
    ])
}

And shortly

plansListTableView.isEditing.toggle()
