Full Calendar showing previous month in header

Never mind,I updated to the new version and that fixed it. thanks!

I am having the same issue. It shows Dec 2020 but it does display January 2021’s events. (https://www.grantcounty.org/events/)

I have the newest version of Events Manager (version 5.9.9).

I have tried re-uploading the files.
I have found the Map List Pro conflicts with the plugin but it causes the dates and times dropdowns to not work.
I have through all the settings multiple times but I still see Dec 2020

Check out this thread, this is what fixed it for me (enabling Dev updates from the Events Manager settings and updating the plugin fixed my issue.):
