Stick to the top of the blog

Hi guys – I have a client using an old theme, specifically:
https://github.com/hyprtxt/bootstrapfour
https://blog.getbootstrap.com/2015/08/19/bootstrap-4-alpha/

The option in the individual blog post to Stick to the top of the blog is not working.

So my question is ‘how does this work from a code perspective’ ?
What functions should I be looking at to see where this is broken.
Unfortunately, I don’t know if this checkbox ever worked or if this is something new.

When I look at the query being rendered on the blog index page, there is nothing in the query to identify what may or may not be stick:

SELECT wp_posts.*
FROM wp_posts
WHERE 1=1
AND wp_posts.ID IN (283,4259,285,3914,3915,3916,3917,35,287)
AND wp_posts.post_type = 'page'
AND ((wp_posts.post_status = 'publish'))
ORDER BY wp_posts.post_date DESC

It just list the posts by ‘menu order’.

Can anyone tell me how the sticky part is supposed to work, and where I might find the WordPress code that control this??

Thanks!
