I’ve found the issue here. You’ve used a wrong “Post Meta Name”. Instead of idea_like_count, you just need to use like_count, as this is the name used by Metabox. This way the value will correctly be saved in the correct database. Also, for the second and third column, there was a missing Post ID reference. I’ve added this as well. Also, make sure that Metabox adds the value 0 by default for each new created post. Otherwise, the button will be initially empty.
