Configure Clouds - no credentials visible for vSphere Cloud

After updating to new jenkins version, the clouds configuration page has moved.

When accessing the new config page, the "Credentials" dropddown for my existing vSphere Cloud is "none". Before the update, I had configured credentails for that cloud. Also if I open the drop-down, the list only contains "-none". Also if I click "Add" and add new Global credentials, the DropDown keeps empty.
