Hi Shikoro,
We have just released a new update of Grimlock for The Events Calendar. Updating this plugin to the latest version should fix this issue.
After the update, the problem should now be fixed. However, you might still be seeing the issue because your browser cache is showing you an older version of the page (browsers do that to load pages faster). To see that the issue is resolved you will need to empty your browser cache and reload the page. If you want to read more on what browser cache is and how to clear it, here is an article that might help you: How to Clear Internet Cache in Every Major Browser.
Kindest regards,
