LR is adding shadows while creating Panorama pictures

Dear Community,

I'm normaly using LR for creating panorama pictures which I did with my DJI drone. But in the last few weeks I suddenly got problemes while creating these pictures. In some cases LR wasn't able to create the panoram at all, in other situations it adds really strange looking "shadows" to the picture (No shadows in the raw pictures).

(obviously botton left, botton right)

Anybody an idea how to solve this problem?

Thank you for you help.

Best regards

Jannik
