Possible To Flush Out Pre-existing Schema Types?

I am attempting to completely rewrite footer.liquid. Unfortunately, there are pre-existing fields which I am no longer using which are causing errors to be thrown when I attempt to save my file. For example:

• Error: New schema is incompatible with the current setting value. Invalid type value for block 'linklist'. Type must be defined in schema.

I understand that this is because I am not using an "id": "linklist" in my new schema. Is there a way to flush out these pre-existing schema types so that I don't have to include it in my schema?

If you delete the section in the theme editor and then readd the section after, that should solve the problem.

Alternatively, you could find the settings_data.json and remove the current values associated with your footer section.
