Panoramic stitch problem

[Ste26602316pm2y]

Using PS 21.0.02 on my Windows 10 Desktop I stumbled upon the Automate - Photostitch tool, loaded a few screen grabs into it and was impressed with what it produced (below), however I have tried to recreate the effect with better quality frames, but simply cant get it to replicate the original, all attempts appear like the lower image, I have tried many times, with different settings but getting nowehere, It as though the blank canvas setting isnt long enough perhaps.

Can any anyone assist me or point me in the right direction ?

The image below is actually one picture, PS has split the panaramic shot.

With the higher res images, have you tried this in Camera Raw. Sometimes it works better than the stitch in PS.
