Time of Day routing plan

Question

Hi,
I was looking around in the program software just before the daylight savings time change. I did not know that the system would change automatically. Anyway, somehow I created another Time of Day Routing Plan. It hasn't caused any problems but I get warnings on the history list. There was a Time of Day Routing Plan 1 already in existance. I accidentally created Plan 4 but all the numeric info is exactly as it is in Plan 1 and I would like to delete the one I created by mistake. Can you help me?
