Not a bug.
All photogrammetry tool for avoid wrong rotation tags after preprocessing or from camera decided treat different rotation as different lens group.
So first step after copying images from SD card will be better remove rotation tag from images.with Exiftool.
“c:\Program Files (x86)\Exif Tool\exiftool.exe” -Orientation=1 -n *
(do not forget delete *_original files when process finished successfully)
Ungroup images only in final align refinement if needed.
