Campaign Medium, Source and Group not showing since Matomo 5 upgrade

Since we upgraded to Matomo 5, the campaign medium, source-medium and groups are not showing anymore. We haven’t changed anything on the tracking.
What should we do here?
Thanks!

Update: the data is now there, but only from today and up until we did the matomo 5 update. Nothing in between. The Campaign names and keywords are shown for the whole time. Is there something we could do here?
