Comment:

 Hi there, welcome to WordPress Trac! Thanks for the report.

 As previously noted in comment:5:ticket:19074, `save_post` fires twice for
 any post type that supports revisions:
 * First, it fires for a new revision being created.
 * Then, for the post itself being updated.

 When using the `save_post` hook, you should check the post type of the
 post object before doing anything. Some examples might be helpful:
 https://developer.wordpress.org/reference/hooks/save_post/#user-
 contributed-notes

 Alternatively, you can use the
 [https://developer.wordpress.org/reference/hooks/save_post_post-post_type/
 save_post_{$post->post_type}] hook that only fires for specific post
 types.

 This works as intended, I don't see a bug here.
