Updating UILabel and Deleteing row from UItableview - ios

Question

I have a UITableview and I populate the rows with data from an api.
I have made code to update the label of the item in the cell row if more than on of the same item is added to the tableview. If a new item is added it populates a new cell row with the information.
I am trying now to use the UITableview editing method to delete rows from the UITableview.
I have no problem with deleting rows but My problem is that how can I delete the quantity if the item in the cell row is more than 1 and if the quantuty is only one delete the cell row.
I am getting a strange bug when trying to do this.
My code minuses to many times, please see my code and screenshots.
