Thanks for your reply!
Do you know how it can be disabled in the backend? In the frontend it’s good that all filters are on, but in the backend it shouldn’t be happening.
(I’m not very technical with this kind of stuff)

check this plugin, it’s enabled by default.
$this-\>subscribeEvent( **'Enlight\_Controller\_Front\_RouteShutdown'** , **'onRouteShutdown'** , -100 );
