Non-editable folders

I have a problem, maybe a bug? If I create a subfolder in Collection, I can not delete or rename it right away. Solutions?

maybe because subfolders are not supported in the SC5000 yet. I would prefer them, too

Certainly they are supported, I have always made and used them. In conclusion I resolved going to the SSD folder and deleted all the rescue files. I made a new collection with modified subfolders. Cmq after me there is a problem with the software.
