Hi Lena,
The events seem to be showing up in the calendar ok. The mix of posts and events seems to be a feature of your particular theme.
I would normally ask that you switch to the Twenty Seventeen theme and disable all non Events Calendar plugins to see if it’s a theme conflict, which this seems to be. Unfortunately, we can’t provide support for third party theme or plugin conflicts.
I would start with the theme settings to see if there is something in there that may dictate which post types show up on your homepage. Make sure “tribe_events” post type is added to the feed.
Let me know if you have any other questions.
Thanks,
Sky
