'save as jpeg' while in isolate

We always made pictures of our seperate sheet metals by isolate the body in a complete welded part and then 'save as jpeg'. We then only got to see the isolated sheet metal. Since we work in 2025 the problem is, when I am in isolate, and go to 'save as jpeg' and save the file, the isolate gets "supressed" and it saves the complete part instead of the isolate. I can't find any options to make changes to. Anyone else experienced this problem before and a way to solve this? 

This was before in 2023 when we did 'save as' in isolate

 

This is the result now of that same 'save as' function in isolate
