Multisite?

We have a problem with the notifications. We have a multisite installation. Gamipress is enabled throughout the network. Page 1 (main page) creates the achievement. Learndash is installed on a subpage.

We have created a new achievement on the main page: “Complete a course”.

If the user now solves the step on the subpage with learndash.
The title of the notification does not show the title of the achievement with the shortcode {title}.

It shows the title of a learndash lesson.

Both have the same post ID.
