Team Edition: v3.2.0 to v3.3.0: empty "Recent Active Users"-List

Dear crew,

after upgrading our Team Edition Server (Postgres-DB-backend) from v3.2.0 to 3.3.0 the "Recent Active Users"-List accessible via: System Console -> Teams -> "TeamName" -> Team Statistics is cleared and stays empty.

This feature worked on v3.2.0 and no configuration items have been changed.

Any ideas?

Best regards,
Nico
