Picture 1: Looking through one of the lenses in a mirror.
As I would expect, one lens looks transparent in the
reflection, the other is black:

Picture 2: Turning the glasses to look from the wrong side
in - both lens reflections look transparent:

I have trouble understanding the configuration of your experiment. A diagram
would help.

For example, I do not think you literally mean "in a mirror. The lens is
certainly not in a mirror. There may be an image formed by the mirror.

There are a number of ways in which the stereo effect can be achieved. The
polarization orientations can be at plus and minus 45° rather than
horizontal and vertical. More likely, circular polarization with a quarter
wave film is used.
