he problem is related to the parametrized scheduler, as this schedule:
H(50-57) 22 * * 3 %Project=test1....etc
H(50-57) 23 * * 3 %Project=test2....etc
Only gets triggered the first time, so every Wednesday, it triggers the first one and NOT the second one.
This is just an example of Wednesday, I've got other such schedules for the rest of the days of the week, but only once, so they work OK.
