Hi Sarah!
Thanks for sending out the screenshot.
It seems I could see it the first time, but it hides after resizing to mobile and then going back to desktop, so it seems there is a glitch somewhere.
Having a closer inspection I can see some styles hiding the filter bar on mobile and are coming from the fusion-global.css stylesheet. These could be coming from the Fusion Builder or Fusion Core plugins which I see you are using.
Do you see any difference when deactivating those plugins? Let us know about it.
Thanks,
Victor
