SEMrush Software Showing Duplicate Content, Meta, and Title Descriptions

I am using the SEO tool, SEMrush, which completes a site audit for lawenforcementsocialmediatraining.com.

I have attached screenshots where it is indicating that the following pages are showing duplicate meta descriptions, titles, and content:

https://lawenforcementsocialmediatraining.com/categories?start=0
https://lawenforcementsocialmediatraining.com/categories
https://lawenforcementsocialmediatraining.com/blog?start=0
https://lawenforcementsocialmediatraining.com/blog

I only have menu items for /categories and /blog. I'm not sure how or why it's reading the pages with the start=0. Because they don't have a menu item associated with them, I can't change their meta descriptions or titles.

Is there a setting in EasyBlog configuration which will correct this, or do I need to create some type of menu item?

Thanks,
Mike
