Things are created but not deleted from myopenhab!

Hello!
Things are created but not deleted from myopenhab !!!
This is normal?
How to delete things through the cloud?
I would be grateful for your help!

Hit the “Delete Items and Events” button:

Then everything will be deleted, and I need to delete the secret things.

No, just the items you exposed to the cloud.

In any case, I need to remove not the item but the thing. How can deleting an item delete a thing?

There are no things in the cloud, just items.

Ok!
