I have about 12 tasks that have to get done at work everyday. All these tasks are completely differnet so I made a seperate task for each one and numbered then 1 to 12. Well, numbers 10 to 12 do not appear under 9 but under number 1, like this
1
10
11
12
2
3
4
etc...

Is there sone have to fix this so they appear in the proper order?

Thanks
