Hi sorry about that, for random beats, actually nothing is saved yet, the text is wrong. That's something I need to fix. But I will need to change the save file format and the random beat menu UI too. For normal levels, if you click the level you should see a list of all the beats you have made for that level. You can select one and either edit it or play it as a level. So it will fill slots C onwards. This is what it should look like for a normal level.
