Error when calculating planning in view Planning (No data to display)

Hello,
Recently, I installed projeqtor V8.2.4
- I did my best to configurate projeqtor in interafce "global paramters". (Please see screenshot attached below)
- I created a custom workflow, project, some ressources
- I added some activities where ressources are assigned

Then I openned interface "Planning". Unlucky, I have following problems with planning :
- Not all planning are displayed. Planning is displayed only till current day. Only activities that were already filled by ressources into timesheet are displayed. (Please see screenshot attached below)
- 2 off days (Saturday and Synday) don't have grey colour. They are not shaded (Please see screenshot attached below)
- When right click into activity planned in current day, I have error "No data to display. Planning calculation required" (Please see screenshot attached below)

I need to get a complete planning.
Any help please.

Thank you in advance.
