HDMI Output reversed left to right. Em1 Mkii Firmware 3.1

I was recording a scene on using video but outputting the clean HDMI to an ATOMOS Ninja Flame to record rather than using the internal SD card ( as i have been doing for a few months now). All has been very good ( apart from a hiccup with firmware 3.0 but fixed with firmware 3.1)
However I noticed the last recording the scene was reversed left to right. This has never happened before. I am going to do some experiments as to possibilities as to why but I thought I would ask if anyone has experienced anything similar,
The only difference I had in this recording was that i had flipped the camera screen out and turned it so it faced the scene ( as opposed to normally where is facing away from the scene). This was because the camera was in a corner on a tripod and I needed to look at the camera screen from the front of the camera.

I wonder if this change affected the HDMI feed out.

Anyway i will try some experiments but would appreciate any comments in the meantime.

This is a deliberate feature. You have set the camera into selfie mode, which allows someone making a selfie to admire themselves in the mirror.
