I am a new user and messing about in the training mode.

I can open various markets from the market navigator (say all of the races at a particular meeting) and place bets using the ladder or the multi bet tool.

If I go back to a market that I have previously opened but closed then either:
a) neither the grid nor the ladder will open; or
b) only the grid will open.

This is even though I have a default to open both. Even if I click on "open ladder", nothing happens.

Has anyone had similar problems? Maybe I am just missing something obvious.
