Operator Selectable Tone-OST Tk-890H

I purchased a radio Tk-890H everything powered up ok and i can read from radio no problem but when i try to even put that code plug back in as is without changing anything i get a error saying.....(Operator Selectable Tone with an only OST name is programmed).......Ok no big deal open OST menu and sure enough there it is #2 so i delete the name and close it and still get the error on write to the radio,went into dtmf and turned off everything because i'm not usng any dtmf on this radio....Any ideas or am i missing something stupid
