[C1v22] Panorama Stitching multiple row

Sometimes C1 creates multiple row panorama and sometimes not.

The first setup is DNG by a DJI in 3x3, which work very well. The second setup is CR2 by my Canon 5Dm3 in 3x9 which C1 cannot stitch.

In both cases the overlapping is appx 1/3 to each side.

With Panorama Studio Pro 2.x in 2013, I have created a panorama of the CR2 (afterwards converting into TIFF16). Therefore, it is not an issue of the images.
