Hi michelle c
This i normal don't worry!

I think the dolphin trainers call this the "new tank" syndrome!! When the dolphins get moved from the training tank to where they are expected to perform they seem to forget what they have learnt.
Just work through earlier stages when you are in a new area and soon they will do what you have taught them any where you ask. It also proves that the behaviour or action is truly confirmed.
