Problem with timesheet - Nothing appears

Hi, I don't know where I'm doing wrong, but when I click on the timesheet, the original page remains displayed. I have to resize the window to at least 1/2 width and click on the timesheet again. Only then will the correct display occur and I can maximize the browser window again.
Thanks for any help.

I launch the application, the homepage is displayed. I click on Projects - projects are displayed, I click on activities - activities are displayed, etc. I click on Timesheet - the original page remains displayed, the timesheet report is not displayed. I have to minimize the browser window (at least 1/2) and then I click on Timesheet and it shows the timesheet. Then I can maximize the window. This happens in Firefox, Chrome, Edge. Apparently this is a bug in the user profile as this only happens with my profile. When I log in as admin, everything works as it should (even with the window maximized). Is there any way I can reset my profile settings? .
Error log is empty.
