Photoshop Ecosystem Tutorial can' advance within segments

Like Next button is not available or does nothing? I think you have problem with strict rules that each and every step must be executed in details so if instruction is to select some tool or click on some layer then you must follow exactly as described or instructed. 

At the beginning it is forcing me to click on square in front of the layer, otherwise it is not possible to advance even Next button is active and clickable - Get to know layers tutorial. It is sometimes strange and non intuitive/forgiving and perhaps not enough clear, otherwise everything is function so far for me on my side.
