Hello @nnyorker, welcome back to the forums!
Good question. Those are actually notices in the console and do not signify any errors–in other words, it’s diagnostic information about the calendar’s assets and performance and has no impact on your actual site.
That said, we know it’s not highly ideal to see those messages in the console, so we are looking at removing them in a future release. In the meantime, however, rest assured they will have no impact on your site.
Does this help answer your question? Please let me know. 🙂
Cheers,
Geoff
