The "1 2 All" option for displaying bars as described in the demonstration for "Building Blocks 2 Section 7 Melody 7: 4 Bars" is not available within Building Blocks 2 itself. Ive tried both Firefox and Edge, and have looked at other challenges, exercises, and the Studio itself and it is not present in any case. Attached image shows a side by side of the video from the demonstration stated earlier along with the challenge of the same section showing the option not present.
