navigation bar button text disappears - swift

Question

I have 2 nav bar buttons at the top of the screen, one with an image an another with text like so:
When I present a new view controller with a new nav controller/root controller and then dismiss it, going back to the same view controller, the text disappears like so:
Here's the code for the view controller
override func viewDidLoad() {
setupNavBarButtons()
}
func setupNavBarButtons() {
let searchImage = UIImage(named: "search_icon")?.imageWithRenderingMode(.AlwaysOriginal)
let searchBarButtonItem = UIBarButtonItem(image: searchImage, style: .Plain, target: self, action: #selector(handleSearch))
navigationItem.rightBarButtonItem = searchBarButtonItem
let filterBarButtonItem = UIBarButtonItem(title: "Filter", style: .Plain , target: self, action: #selector(displayFilter))
navigationItem.leftBarButtonItem = filterBarButtonItem
}
func presentAccountController() {
let accountController = AccountController()
accountController.listController = self
let vc = UINavigationController(rootViewController: accountController
presentViewController(vc, animated: true, completion: nil)
}
The controller I'm dismissing to return to the original view controller:
class AccountController: UIViewController, UITableViewDelegate, UITableViewDataSource, MFMailComposeViewControllerDelegate {
override func viewDidLoad() {
super.viewDidLoad()
setupViews()
view.backgroundColor = UIColor.rgb(245, green: 245, blue: 245)
let closeButtonItem = UIBarButtonItem(title: "Close", style: .Plain, target: self, action: #selector(dismissController))
navigationItem.leftBarButtonItem = closeButtonItem
}
func dismissController() {
self.dismissViewControllerAnimated(true, completion: nil)
}
I've tried calling it in viewWillLoad, viewDidLoad, viewDidAppear. Still no change and the bug still occurs.

You can do this and create a frame with a wide width when you create the button
lazy var filterButton: UIButton = {
let button = UIButton(type: .system)
button.frame = CGRect(x: 0, y: 0, width: 60, height: 30) // Set the width here to make it wider
button.setTitle("Filter", for: .normal)
button.titleLabel?.font = UIFont.systemFont(ofSize: 18)
button.setTitleColor(UIColor.white, for: .normal)
button.addTarget(self, action: #selector(filterButtonTapped), for: .touchUpInside)
return button
}()
var leftBarButtonItem: UIBarButtonItem?
override func viewDidLoad() {
super.viewDidLoad()
leftBarButtonItem = UIBarButtonItem(customView: filterButton)
navigationItem.leftBarButtonItem = leftBarButtonItem
}
#objc func filterButtonTapped() {
print("Filter button tapped")
}
