Selecting more than one option

Hello.

I have tried to look for anyone with this problem, but I can’t find anyone, so it must be something on my side.

I created a simple Filter set to try it out, and added it to the sidebar. This site is about guitars. I want people to find a guitar based on options they want on the guitar. I only added in the taxonomies “colors” and “tremolo bridge”.

When I choose colors, I can click as many as a want to view, but when I choose one checkbox from tremolo bridge, I don’t get to choose anymore. it’s like its saying “there are no options with another bridge with the one you are choosing” which would be correct, since a guitar doesn’t have two bridges. But with that logic the amount of other colors should have gone down after clicking, since all guitars doesn’t have all color options.

I want users to be able to choose all the options they can from one taxonomy, and to choose all the options of what is available from the previous chosen taxonomy etc. in the order they want.

Thanks.
