I only just got the new UI myself, but I have seen other people here mention that they got the new UI, then the old UI, it seems to be a bit inconsistent...
So far, I've been getting the new UI since it was switched over to my account, but I may have the same behaviour as you later, I will watch for it... my assumption is that due to the rollout nature of the tool, and because Adobe has a lot of servers to handle all their clients, it may just be a result of the code references not yet updated for your account on all servers yet.
I am not sure what you mean by you are "not able to use scheduling options"?
You chose an account "Click 51" but you haven't yet provided a location. The account is the information about where and how to connect (i.e. FTP server X, with account Y, and password Z), the Location specifies which folder to put the content in... the tool doesn't just assume to add the file to the root each time, and while you can drop it in the root, you just have to tell the scheduler to do that...
Accounts appear to be re-usable, Locations need to be specified each time (likely so users don't have to save multiple "accounts" with different folders for different extracts.... they can set up one account, then choose a unique location for each request.
