Model filtering works badly

Since yesterday, the model filtering works badly. To be more precise, this is what happens: * When I want to filter by tasks, I can do it only by the tasks already displayed. Clicking on the "+44+ does nothing; * The "Reset (tasks/ libraries, etc) link doesn’t work; * I cannot filter by two or more tasks, libraries, languages, etc. Only the last clicked option is taken into account * The “Parameters” slide bar does not work. It does nothing when I click and drag it. I use Edge, but the behaviour is the same on Chrome. It doesn’t matter if the browsers’ extensions are turned on or off. Both Edge and Chrome are up-to-date.
