Hello,
I have visited your site. Currently your filter using single column. You can use the “2 column” display type from Appearance >> Widgets, so I can check your filters that if they override each other or not. Because at my test site there is no such problem as like in your screenshot.

Also which value do you want to reduce? If you are talking about the value shown in tags for each filter. That value is auto generated and can’t be changed.
Best Regards.
