easy timer bug

I have 3 Timer declared by app_easy_time.one is periodic by one second , the second one is called in some occasion, the last one is call evey 30 second at random time.
With this three timer,the second timer callback is called not correctly ocassionly .I believe it is called by the first periodic timer.
If i use only the first two timer ,eveything seems ok.

update: some simplified code ilustrting my timer setup,the wrongly triggerd hanler problem was my fault,but another problem occurs.
