Sidebar area

Hi once again, I need help with the sidebar area. Everything looks perfect until I go to other subpage from menu (kierowcy, zespoły etc). Sidebar is still there but it sholudn’t be. I tried some changes in reading settings – static front page and moving widgets to the “front page right bar section” but widgets don’t work there. Are there any solutions to hide widget’s sidebar on other subpages?
