I created a custom Cybertronian race for a Homebrew campaign, but my players discovered that it doesn't come with any language options, not even Common. I eventually added a Racial Option that is supposed to add Common and one other language. However, it only adds Common to the Decepticon Subrace, leaving Autobots language-less and Decepticons only possessing Common. This is despite me adding it to the parent Race, not the Subraces.

Try editing and saving both subraces to see if that re-syncs them with parent race.
If that does not work, please provide a link to your homebrew. Please do not publish it. Moderators can view unpublished homebrew with a direct link.
