I have modules assigned to menu items. I noticed after upgrading to Joomla 5.1 that all modules with position right are shown on login page while they are not assigned to that page. I tried to fix this but cannot solve. Do you have an idea?

The pages where the modules are shown wrongly are assigned to menu items, while these modules are not assigned to these menu items. I tried a condition to exclude modules for these pages by url and component without effect. No matter what I try, modules remain visible on pages which they are not assigned to. I have this issue on a few pages, all other pages are correct.

Indeed, the Joomla default template solves the issue, problems occur with the template I use. I look further into this. Thanks for pointing me in this direction.
