Two mysterious calendars on iCloud

Hi. Two mysterious calendars with weird names (such as this: 770BBD7A-10EE-4154-9274-A459CBC2919B) have appeared in my iCloud account. I have no idea what they are and how they came about. There are no events associated with them. No matter how often I have tried to delete them, they come back again and again. I am assuming that my calendar database has probably gotten corrupted (don't know how). With the result that some of the events I schedule, don't show up on my iOS devices.

What should I do to fix this problem? I use Fantastical, but it shares the library with Apple's Calendar--so I am assuming there is some problem in my library folder.

Any help will be gratefully received.

Hurrah! I finally figured out a solution that worked. I disable iCloud calendars from all my devices. Then went to the web interface at icloud.com, made the corrections (deleted those mysterious calendars that had popped God-knows-from-where), then one by one enabled the iCloud calendars in all my devices. I am all set now.

Safe Boot from the HD, (holding Shift key down at startup), does the problem occur in Safe Mode?

Safe mode attempts to repair Disks & clears lots of caches, so if Safe Mode works try again in regular boot.

PS: As I continue to investigate what's wrong, I have come to the conclusion that the "Home" calendar on iCloud has probably gotten corrupted. Events in all of my other iCloud calendars are showing up correctly, except the "Home" calendar where some events get synced and some others don't.

And there is the presence of those two mysterious calendars I mentioned in my first post (see above).

Has anyone had a similar problem? It's so puzzling.

Thanks for your suggestion. I tried it but it didn't help. Nothing changed. I also tried Disk Utility and First Aid. Again, no change. I tried to add a test calendar to iCloud--and now I can't even delete it! Something is wrong, but I have no idea what it is. Oddly enough, while these mysterious calendars show up on my iPads as well, the "home" calendar seems to be behaving normally unlike on iPhone. The problem is my Apple Watch syncs with the iPhone, so a few "home" events don't show up on it, because they don't show up on the iPhone itself. What a mess!
