Hi Seadar,
Thanks for reaching out to us! I would be happy to help you 🙂
I had a look at your website, and it seems there’s a JavaScript/Ajax problem. If you go forward to June, and then backward to May, you don’t see May’s events anymore.
There might be a conflict somewhere with a plugin/theme. Could you switch to a default theme such as Twenty Seventeen to see if you still have the same issue when looking at the lunch menu? Then, could you try to deactivate all plugins except for The Events Calendar and Events Calendar PRO, and check your lunch menu?
Ideally, you would save your database and your php files prior doing those tests, and you would do them on a staging environment. For more information, please read our guide about how to do testing for conflicts.
Cheers,
Jeremy
