Hi Ines!
I’m sorry you are experiencing this issue. Let me help you troubleshoot this.
First, could you please send us a screenshot from the edit event page that shows the recurring event options for the event you are having problems with? This way we can try to reproduce the issue on our end.
When you say that you get weird bugs, what exactly isn’t working? What steps did you make that resulted in the issue? Let us know about this.
Also, when coming back, please make sure you share with us your latest system info by following this guide > https://theeventscalendar.com/knowledgebase/sharing-sys-info/.
Thanks,
Victor
