Cash tender randomly duplicated in tender screen

I've been having an issue w/ RMS SP2 where the "cash" tender shows up twice. This especially occurs on a recalled invoice. I thought it might have been because I changed the tender order (because of the 2nd issue) however I ran a new transaction and then recalled it and it still happened. I had to change the order because when using the touchscreen keyboard if you push the "cash" tender button it selects the 1st tender type in the list even if it is not cash and when you select the tender type that is top in the list it selects "cash". The quick fix was to make cash the top tender but I don't like doing that just incase someone accidently passes a coke or something in from of the barcode reader and tenders a transaction for over $1 billion. It's not a critical issue but if anyone has a solution please let me know.
