Remove Filter Option on Facebook App Integration

[tanyarhe]

THIS IS TIME SENSITIVE. Help! I have my store integrated with Facebook/Instagram. The problem is that it's allowing filters for brand, which is disabled on the shopify store settings. We don't want our brands shown or available. How do I remove this filter? I've searched high and low for the settings and haven't been able to locate it. Any advice, code, or ways to fix?!
