You have event cases where the Front Panel is locked until the event is handled such as for the Ready button. You also have multiple event structures that are buried inside a case structure. That means the event structure won't be executed to handle the event unless you happen to be in the correct case of the case structure.
So if you are in your cal cell state, but hit the Ready button, that event never gets handled because the event case is handled in the Hookup case, the front panel is locked, and there is no way to do anything else on your front panel.
