Hi Ruud,
Thanks for reaching out!
I did some testing on my end but was not able to recreate the issue; the correct events are showing up when I search by title. Can you check other post types (such as Pages or Posts) to see if the same issue is occurring there? If not, testing for conflicts with your theme and other plugins would be a good place to start to find the source of the issue.
You can also give our Advanced Post Manager plugin a try, which provides some additional filtering options for events on the back end.
Let me know how that works! If you do find any conflicts, can you please share your system info with me, and I’ll be happy to take a look and see what I can recommend to get them resolved.
Thanks,
Jennifer
