Inconsistent stability for left and right inverted walls

I have a wall with a 2 x 2 space gap and wall above it like so
[][][][]
[] []
[] []

(edit ; Even in the ‘preformatted text’ tag the above doesn’t preserve whitespaces. it’s a stonehenge looking the thing, the column on the right should be right aligned…)

Appropriately, the stability of the top two wall pieces over the unsupported section is < 100.
I added some left and right sloping inverted wall pieces to the upper left and upper right of the gap to buttress them.
The Left inverted piece contributes stability in the way that I expect, and the right one does not. Even stranger, it appears that the right piece contributes more but that stability isn’t transferred higher up to the roofline - where as the left piece contributes less but it is transferred. So to get my roof to work the way I want, I have to flip a left around and use it inside out on the right side, which looks kind of stupid.

Please provide a step-by-step process of how the bug can be reproduced. The more details you provide us with the easier it will be for us to find and fix the bug:

1. Build the above structure. Seems to work for a variety of tiers (Insulated, aquilonian)
2. Inspect stability with repair hammer
3. Become confused

I had this exact issue recently when building. I found that I had to use ceiling tiles, another floor up, to bring enough stability over to lower a wall onto the Right Inverted Slopes.
