Timesheet 00:00 notation remove, if nothing is.

In a timesheet I have done almost everything except the last column P.
Can you help me with a 00:00 format in a time sheet?
If I do not work one(1) day will show up automatically 00:00
please note ONLY 0:00 designation
highlighted in red.

The blue columns that I can fix with the help of forum members.(mr.dibbins 10 times thx)
But my knowledge is not so far that i can do. Everything step by step I almost can
do everything except,VBA,PHP, and column P.
