I am in love with the Read more theme although there has been one challenge. The Feature slider is not working. I have enabled it in the customizer but it is not showing other option in the select category list. instead, it is showing me uncategorized and I have created my own category. kindly assist in making the slider showing. thanks
Please check is there any post assigned on that category or not. If there is an empty category, it may not appeared on the dropdown. Make sure that post have featured image as well.
Please try once and let us know.
