reactions - emojis don't work

[canina]

Regarding the forum that was upgraded a few years ago to version 2.25
At the time the owner did not use reactions with the emoji, he was content with the simple like button.
Now he asked me to make it possible to have several options for emojis, so I marked on the /admin.php?reactions/ page all the emojis that would be active, but for some reason on the users side they don't appear at all.
Is there another place that needs to be changed for this to work?
Thanks
