Missing (non Default) Library Folder. It exists but can't be seen

Hi, and thanks for this great forum!

I've tried sorting this problem but haven't seen an answer specific for my problem.

I created a library called "Utilities" (for my portable utilities that I use regularly.)

It is there but it is no longer visible and I can't recreate it from Windows Explorer. When I try to recreate it I get the message:

"Do you want to rename New Library folder to Utilities (2). There is already a folder with the same name in this location.

(I tried restoring default folders Libraries >>> (Right Click) Restore Default Libraries as well, but of course. nothing happened.)

When I go to:
C:\Users\Daffyd\AppData\Roaming\Microsoft\Windows\Libraries

the Utilities library is not visible and can't be recreated as I get the same message as above. (But I can create a regular Utilities file folder, but needless to say it doesn't show up in the Windows Explorer Libraries)

I already have folders visible:
Control Panel >>> Folder Options >>> Show all Folders
Control Panel >>> Folder Options >>> View>> Show hidden files folders and drives

I'm at a loss? Suggestions?

Thanks for taking the time to read my post.

Thanks for the welcome and suggestion Brink!

I tried doing that with the cmd prompt (also right clicking and running as admin), rebooting, but no luck.

OK! It's solved. I re-did the final steps and this time Utilities has appeared!

Many thanks Brink, your a wiz!
