Information changed when exported back into LRC

After exporting a RAW (DNG) processed image back into Lightroom Classic LRC I find a lot of the original info has been changed, see below.
The ISO changes i.e. original = 1000, processed copy 1= 1008
Focal length changes from 700mm to 697.9mm
The aperture and shutter speed disappear.
The capture date is replaced with the date the Topaz Photo AI processed the copy.
My copyright info is removed.

These are the changes I have noticed on my Windows 10 PC, but there may be more.

Hi John,

I used the RAW plugin.


Would you mind please take a screen recording of this behavior so I can see exactly what is happening.

Loom is a great free application for this : Loom | Free Screen & Video Recording
