[Plugin: Smooth Slider] Cannot Delete Custom Fields

I’m having trouble deleting the custom fields under every post since the upgrade to 3.0.1. Every post I create now adds 2 custom fields automatically, ‘slider_style’ and ‘slide_redirect_url’ and at the bottom, slide link URL automatically fills in. I can’t delete any of them, and they are showing under the Meta information on the frontend because I need to use custom Meta fields for other things in the site.

How do I delete those custom fields so they don’t show up on the frontend? Frontend looks like:

* slider_style: default.css
* slide_redirect_url: https://myclientswebsite.com/the-post/
