Can't create another subscription plan

[novatke]

I have created three of these already but now as I am trying to create a new one, when I hit next - it looks like it's processing it but goes nowhere.

There is no error message. It does not process behind the scenes and shows up on the home screen.

I have redone this many times after restarts and relogins 

Is there only a certain amount of subscriptions and if so, how do I delete the old ones to make room?

Any help is appreciated
