Problem with creating events for a Facebook group. How to decide?

Question

Facebook

Previously, when creating a meeting for a Facebook group, news about the meeting was published on the group wall, the meeting itself was displayed in the "Events" tab in the group, and "Event for *group name*" was written in the header on the meeting page.
Now, when I create a new event, it is not published in the group on the wall, is not displayed in the "events" tab, and on the page of the event itself it is not written that this is an event for the group, just the name of the organizer is written.
For previous events, I sent out several thousand invitations to the group members, but this is hardly connected and plays a role.
How to solve this problem?
