Filter content not showing immediately after openning the filter on mobile

Hello,

I have noticed that the filter behaves in not the most user friendly way on mobile. When you click on the button “Filter” it does not open the filter with its contents but another label that has to be clicked on in order to show the categories. This step looks like the filter is broken and some users may not understand that they have to click once more on the arrow.

How can we alter the behavior so that the categories are shown straight after the first Filter button is clicked on?

Regards,

Stefan
