I actually found a solution! You need to set the Edit the Neo Geo platform, and set "Scrap As" option to Arcade. It will display the retroachievements in the details view. You need to make sure the name is the same as the retroachievements.org website otherwise it won't show either.

I have the same issue. If I change the Neo Geo games platform to Arcade it works ( as long as the name matches the retroachievements.org name ). I would prefer to keep them as Neo Geo platform though. Wish there's a fix for that.
