This layout glitch appeared in many issues before. Now when the basic site layout has been overhauled and looks fine this glitch is also worth attention.
In the grader report view blocks are always located on the left hand side and there is no space between them and the main region left. The right hand side of the main region is also not aligned with the breadcrumb as it obviously should be. See the screenshot.



Can't replicate this issue.
From version 1.2.4 the margins are modified and should look well in computers (still having some problems in mobiles)
