Actually, this is not a bug, but a result of a development/enhancement. In the Composite Settings panel you have the option to define a skin-end pen. Previously the corner connections in the floor plan were not taking this into account, but now in AC22 they are considered (as you can see on the green selection highlight, the connections are properly made in the floor plan as well, instead of joining the 2 walls diagonally).
I attached pictures of how this works in AC21 compared to AC22. If you set up the skin-end line to be the same as the skin separator, this shouldn't be an issue.
