Big image size after a rename

I currently experience a strange effect:
When I rename and save a "normal" jpg file I had exported from Lightroom (2560*2560, with Meta data) bridge "blows up" the image.
From before 4.4MB the image now shows 26.5MB!
And size increased from 2560x2560 to 5971x5972!
See attached screenshots.

How that? What's going on here? I checked settings and disabled some Meta-parameters; and also all references to raw data I found (that was my first idea that Bridge might save as raw, what imO would be stupid 😉 ).

I used Bridge many times before and never had this kind of problems!

I this the reuslt of the new "AI era"?

Thanks for any help/suggestion.
I helped myself in sorting in Lighroom, buf prefered continueing using Bridge in future...
