Panorama Creation of stacks creates multiple processes

Issue: Let's say I have 5 images that I want to stitch to a panoramic, but first I want to reduce the noise in them. The AI noise reduction created a dng file and creates a stack of the original and the noise reduced file. When I now select those 5 stacks and try to start the panorama module, it starts 6 actions at once: In the first five actions, it tries to stitch each stack alone, creating 5 new extremely distorted images. Only action 6 opens the panorama module.

This behaviour is new and I never observed it before.

The workaround is to open every stack and select only the noise-reduced images. Then it works as it should.

Lightroom Classic version: 13.5.1

OS: Windows 10

How to reproduce: Create stacks of images that you want to stitch to a panorama. Select stacks and open the panorama module.

What happens: Some mysterious parallel stichting processes start that are not hepful at all

What should happen: Start the panorama module and use only the top photo of each stack.
