Filter Handlers Don't Exist

Hi there,

Great job on getting this started! I really hope to use it and I'm not opposed to paying you for your work. I'm getting the following errors:

Error: handler for civicrm_address > circle doesn't exist!
Error: handler for civicrm_address > flat doesn't exist!

...when attempting to add the filters you've created. Please let me know if you can help me get this fixed. Thanks!
