Automation problem

I don’t know if it’s me but when I record automation moves on the fly, often the moves I make do not register and just end up with one move that is just a slope from the first recorded move to the last (missing out little moves in between).
Am I doing something wrong?
Is there a setting I’ve missed?

Any help would very much be appreciated

I’m using cubase 9pro on a mac.

just discovered the exact same thing - see my new post with video! Never been an issue before.
