I can not update my task progress

I can not update my task progress

I am very happy I can use this great online office tools,but I meet a problem when I use the imdm,I need your help. when I use the imdm,my project role is the manager,but I can not use some function,but the other manager can use it.That problem is in Task&Milestone menu,I can only see the Milstones, I can not see the Tasks，and I can not update my task progress. I think that you can solve the problem.
Thanks!
