Everything is correct. Here it works in the same way. 

I'd suggest you check out the wpForo – Advanced Reactions addon. wpForo Advanced Reactions is an addon that enhances your forum with dynamic multi-reaction features, similar to popular social platforms. It allows you to add a variety of reaction icons, including emojis, icon packages, and emoticons, or upload your own custom images and SVGs.

Please see the attached screenshot, which shows the end of a post of mine on The Choro Forum. As you can see lower left, someone (D Chelimsky) has "reacted". Is that all I should see? Not a thumbs up or down?

Thanks,

Andrew
