I see. … that is odd.
Have you made any customizations/might your theme ship with some precustomized templates for The Events Calendar? To bear this out, could you try our standard troubleshooting steps:
- Please deactivate all plugins except for The Events Calendar/Events Calendar PRO
- Switch to a default, unmodified theme such as Twenty Twelve or Twenty Thirteen
- Test to see if the problem remains
If that remedies the problem, please reactivate everything one-at-a-time, testing at each stage to see if the problem has returned (this will potentially help us to zero in on the root cause).
Let us know how you get on!
