shortcode for jquery v2 slider settings

Apologies if this was posted somewhere but I don’t see it.

Upon recently upgrading Karma, the theme somehow disconnected the jquery2 homepage slider from the actual slides, so the slider shows up as a blank box on our nonprofit website.

Under “Slider Settings” on the homepage, there is a pull-down menu for “Slider Category.” It doesn’t work. The next line for “Slider Category Id” says to “Enter the category ID only if the above category dropdown is not working.” What is the format for this, please? The posts are categorized simply as “slider”. I’ve tried “slider”, “id=slider”, as well as various other combos, including renaming those posts and creating a fresh post in a fresh category. Sigh. Please help, thanks.
