Software indexing problem

I swipe to the right and “delete” appears. I hit “delete”. The stock I swipe is not deleted but the stock under it is. I do this several times with different stocks in the list and it happens each time. A similar problems: I hit a stock and it “opens” the stock below it to show the graph data etc. All this only occasionally happens, usually after I have added a new stock. Your software has an indexing problem. It sometimes does not keep tract of where it is in the list after a stock has been added to the list.
