I see the same problem, and I got a screenshot for you. In the picture below, you see two tasks with a time estimate of 10 minutes each. The total time for the day says 0.5 hours, which would be 30 minutes. Is it possible that you round to one digit there?
I also saw a similar problem when combining estimated times with more than 60 minutes (with total times being values of 10000 minutes or more), but I can't remember how that looked exactly. I'm back from holiday tomorrow and start to use weekplan again, so I might be able to give you more information soon.
