Certain colours automatically overexposed in develop mode

[Daniel Nilsson]

I was planning to reedit some of my favourite pics (from 2016), air to air session with Blackhawk helicopters, when I ran into something that I haver never seen in Lightroom Classic before. All pictures where I have yellow ( can´t use the correct word due to dual meaning)  fields in the background look allright in library mode but overexpose the background to an extreme level when I go into develop mode. It´s been some 7-8 years since I worked with these pictures, but this was not a problem then...
Any clues or hints on how to solve this?

The image has an embedded preview (inbäddad förhandsvisning) that you see in Library. This jpg preview is created in the camera, and will display in Library if you have chosen Embedded & Sidecar under File handling > Build previews in the import dialog. Choose any other option when importing to prevent this from happening in the future.

You should also check the option Replace embedded previews with standard previews during idle time in Preferences > General. In any case, the Library preview should update when you do edits in Develop. (Develop uses its own previews, separate from the Library previews)

On re-reading your post, I see that you prefer the embedded preview over what you see in Develop.

If you are using a Picture style or similar in your camera, there might be a camera matching profile that tries to mimic the picture style, and you can then set this profile to be applied on import.
