Hi Minda,
Thanks for getting in touch with us!
I could not reproduce that issue on my end so let me help you with the troubleshooting.
First, could you please share with us your system information by following this guide > https://theeventscalendar.com/knowledgebase/sharing-sys-info/ ? We’ll see if there is anything strange that would indicate an error from there.
That issue could be a conflict with your theme, another plugin or even some custom code. So, to make sure we are not dealing with a conflict, please go through the steps outlined in our Testing for Conflicts guide and see if you can reproduce the same issue under default conditions.
We always suggest to setup a dev/staging site so you can test things out without disrupting the live site.
Let me know how that goes.
Thanks,
Victor
