Exported Image is in 2 pieces

Exporting an image from Twinmotion results a fault, the image has a split line down the middle, so 2 of the same on one image ? Bug or settings issue ? I have exported images which come out correct, have experienced this on both Mac & Windows machines. Any thoughts ?(image attached) Image-01_002.jpg tia

Looks like it’s rendering in side by side 3D
