I have managed to get slides in different sizes in the same project (see attached image) and I don't know how. I wish for all the slides to be the same size, the smaller which is standard. The course is set to 4:3.
Also, when reviwe the quiz to see the questions I got wrong, the bigger slide is now normal size and when I hover over it, it flickers between the bigger size and the smaller size.
Does anyone know how to get them all back to the same size?
