Strugling with change entity action

Could do with some clarification.
Am trying to automatically assign two entities to a ticket (booking and room) but cant get it right.
At the minute it odly doesnt add the entity to the ticket but then when i close the ticket i get both entities on the top of ticket (but isnt a ticket)…


Adding an order clears the entities, close the ticket and that same set comes back?!?

So you somehow updating default ticket that appears when there is no ticket. On next release you won’t be able to do that.

It seems to be something to do with change entity with can create ticket = false.

Is there a way to update an entity account in an action?
Am using dual entities, rooms and bookings, checking in a room creates a booking entity which also creates a booking entity account, the booking entity name/account is logged in the room entity as a data field and would ideally like to charge to booking account from room entity.

Sorry, better solution, on selecting room entity it also selects the booking entity using the {ENTITY DATA:Rooms:Booking Number} field but still cant work out out the change ticket entity action…
This is what I have;
