there is a bug in that lesson with my poor english i am going to try explain you what happened. when you finish the practice against clock the circle says you have practice "Plans lesson" but you are in "immediately future" lesson so if you can check that please. i do not found the support section in the page that is why i am writting this here

ahora la explicare en español hehe. cuando estas practicando futuro inmediato y terminas la leccion la barra de experiencia dice que has practicado "Planes" pero la leccion no tiene ese nombre ni ese icono. Deberian revisar eso
