Hi noahplemmons,
I'm sorry to hear of the issues you're having removing the filter. There is a button that allows you to delete or edit the manual filter in the advanced settings page - but there is an issue causing the button to be invisible. It is something that our developers are aware of and are working to resolve.
To remove the manual filter now, you need to click where the button should be shown - you can tell when you have the correct spot, as the cursor will change to the "pointing hand". Once this is clicked, you will see the option to delete or edit that filter. Please see attached images for where to click.
