Hey Johan,
Thanks for reaching out to us!
I’ve tested this with my local install by changing my date format to match yours in the screenshot and creating a recurring event to run every Saturday from July 9 to September 24. However, I was unable to replicate the issue you’re describing and experiencing above. The events are showing and linking as expected.
As a starting point, have you tried following our Testing for Conflicts procedures to ensure there isn’t a conflict occurring here with an existing plugin or theme?
Thanks!
