Editing the featured post slider in Simple Catch

I created a blog a few years ago and that included a scrolling slider at the top of the homepage.

I have now returned to the blog to update it but I have hit a snag. I can’t edit the slider any more.

I want to update the slider images but the feature that existed previously appears to have gone (..appearance / theme options / featured slider) Due to an upgrade I think something has changed.

Anyway, if anyone has had a similar problem and solved it please do let me know. Thanks.
