Inversion issue

[mauri.land]

Hi everyone, I'm trying to understand what's wrong with this block.

I've made a simple figure that I want to invert in both direction left-right and up-down.

I need that inversion snaps follow the movement, but something strange is happening: for the left-right inversion I have no problem, in fact the up-down snap follows the center of the side of the square. But for the up-down inversion, the left-right snap doesn't follow the movement properly. 

Where am I wrong?

Move the center of the left right axis FLIP parameter line so that it aligns with the grip.

As an explanation, the grip ALWAYS follows the movement of the parameter.  In the case of the flip parameter, the grip always exactly follows the movement of the CENTER grip point of the flip line.  In your block, you have the center of the left right axis flip line very near the up down axis flip line but the left right axis flip grip is offset farther.  Because of this, when the left right axis flip line is flipped to the other side of the up down axis flip line, the movement is than the movement of the box.  The left right axis grip moves that shorter distance rather than staying aligned with the box.
