Can't use constraints for cell with .xib file - ios

Question

I need to set constraints for a UILabel, but whenever I try to add a constraint for my UITableViewCell it messes up, and the element goes to the top left corner it seems
Here's how I set up my UI elements
Here's how it looks like when I run in a simulator
"Food" is the "English Meaning" UILabel
Here's my code for the cell file that's generated with the xib
class ReusableCell: UITableViewCell {
#IBOutlet weak var arabicMeaning: UILabel!
#IBOutlet weak var englishMeaning: UILabel!
#IBOutlet weak var upvoteButton: UIButton!
#IBOutlet weak var downvoteButton: UIButton!
#IBOutlet weak var upvoteCount: UILabel!
#IBOutlet weak var downvoteCount: UILabel!
var upFlag = true
var downFlag = true
override func awakeFromNib() {
super.awakeFromNib()
// Initialization code
}
override func setSelected(_ selected: Bool, animated: Bool) {
super.setSelected(selected, animated: animated)
// Configure the view for the selected state
}
static func nib() -> UINib{
return UINib(nibName: K.ReusableCell, bundle: nil)
}
#IBAction func ReviewPressed(_ sender: UIButton) {
if upFlag && downFlag{
if sender == upvoteButton{
upvoteCount.text = String(Int(upvoteCount.text!)! + 1)
}
else {
downvoteCount.text = String(Int(downvoteCount.text!)! + 1)
}
}
else if sender == upvoteButton && upFlag{
upFlag = false
downFlag = true
upvoteCount.text = String(Int(upvoteCount.text!)! + 1)
}
else if sender == downvoteButton && downFlag{
upFlag = true
downFlag = false
downvoteCount.text = String(Int(downvoteCount.text!)! + 1)
}
}
}
