AWB removes Full Width options for group and columns OR push them backward

Hello,

Since, I guess, last update, I have discovered that :

1- A group and/or a column block INSIDE the AWB got its “full width” option being not accessible anymore ; eg : if I create a block of 3 columns or any kind of group, the option of making it Full Width (or any width option) disappears on the block’s menu.
Therefore, if my picture is full width, the columns cannot match with its full width and, for instance, a paragraph got a margin with the AWB block which cannot be bypassed or reduced.

2-Conversely, if I put a group and/or columns OUTSIDE the AWB block, then this group/columns got its Full Width option back to normal… but then, the block disappears BEHIND the picture when scrolling, and not over it, when the parallax effect is activated…

I am a beginner here… so bear with my limited knowledge of CSS, please ??

Thank you for your time.
