This happens when you upload the image before it is stitched.
Because of the meta data, Mapillary assumes it’s a 360deg photo, but it expects it as a equirectangular image, not as 2 spheres.
You can stitch them using the mi sphere camera software for a PC (windows only), in the app on your phone, or using the camera itself when you take the photo. Other 3rd party software is available.
If you try stitching on a phone that hasn’t enough CPU, I believe it tries to stitch it at a lower resolution instead, to make sure you at least get some image.
That aside, it’s a 24mpx camera, but that is spread over 360degree field of view. It does make reading text more difficult compared to a 14mpx camera but with only a 130deg field of view
