incorrect display of spheric panoramas

Hi there

I remarked this issue on Version 10.3. Now we have V11 - and the problem still remains.
It’s not possible to create a spheric panorama with the 26 RAW-pictures from a DJI Mini 2 drone.
It still looks like this in the bottom center.

On most of the homepages to present these spheric panos I will need a format of max. 10000x5000 px.
It would be nice, if Lightroom could do this for me. That means… to expand the sky and format the exported jpg to 2:1 format. Is there a short way to do this?
