GameManager fails to display shared group data

I'm unable to see some of the Shared Data Groups in GameManager even when I know the group exists.

The Title ID for this but is 56F9.

There should be 5 groups in this title: "[Bot Arena Group X]" where X goes from 1 to 5. The GameManager displays the first 3 grups correctly, but fails when trying to show 4 or 5. No one in the team is able to see any of these two last groups. But I'm sure the groups exist because they show up when calling the API with postman or similar.
