X access mirror modifier behaving like Z access mirror? Something bizarre seems to be happening where applying the X access mirror modifier mirrors on the Z access and the Z access modifier flips it over the X.

You can see in the photo below that X is selected to mirror, but it's not mirroring on the X. It's flipping on the Z instead.



I tried doing these cursor fixing steps, although it seems like it might be a different problem, since it don't work.

What went wrong? How do I fix it? This is 2.8 Beta.
You must apply the transforms, or avoid the rotation in object mode.
