Can't build an upvote button for the life of me

Some old template have this ready to go upvote block, but for some reason it deletes itself or tells me to update. I just want to be able to upvote and downvote items in that list block. What happened to this functionality?

Hey @ImproveBox,

Will you please mention the Theme name? I would be happy to test and discuss with the tech team to see what’s the reason.
