Howdy Steve,
Welcome to our support forums and thanks for reaching out to us.
I’ve took a look to your site, but I can’t see Filter Bar in there, right? Maybe you deactivated it temporarily?
Do you have an staging site were you can activate it and share the link with me? If an easy CSS snippet fixes the issue I can help you out with it, if there’s no simple solution possible you’ll need to contact Avada Theme Support to report this and see if they got a solution already crafted for that.
Please let me know about it,
Best,
Nico
