Unplanned mass-injected activity in the diary

Hello
we injected 192 activities en masse (all in the same form and with the same options)
they have been well generated in ProjeQtOr's "Activity" menu.

However, when we launched the "Project Planning Calculation" so that they appear in the employees' agendas, 52 of them are not planned!

Do you have an explanation? and what do we need to do to solve the problem?

for information: we tried again to run but nothing helps

Hello,

I have provided you with my import files. All the lines are identical, that's another problem.
cordially

The name of the person in charge is not in question and the date is also different but it is normal since one has different users and one wants to plan in mass ...

If I delete the activities, do not reuse the same structure and the same data and only 10, it works, but it is fast because I can not trust in the injection.
