Why 2 theme plugins affect each other when used on different sales channels ?

[@Moritz Naczenski](http://forum.shopware.com/profile/14574/Moritz Naczenski „Moritz Naczenski“)‍ is the directory where the twig files are located correct?
In here https://docs.shopware.com/en/shopware-platform-dev-en/theme-guide/twig-templates?category=shopware-platform-dev-en/theme-guide in some places it is sometimes mentioned that twig files should be under src/Resources/app/storefront/views/(layout or something else)/ and in some other places it is under /Resources/views/storefront/layout/header.

Which one is correct? Is the problem in directory structure or that I have not generated the plugin by shopware cli console ?
