Why Topaz Photo AI does not save the Exif Data?

I think this is a recent and crescent bug. Now usually Topaz does not save the Exif data! Is it just my problem or have other users had the same problem?

EDIT:
Double double-checked again, and now I am not sure at all. Some pictures keep the EXIF, and some do not(?)
I have tried to replicate the issue to no avail, so until I can replicate the issue, I’ll put that in the “unexplained bugs” folder

Thanks to you, I just checked, and Topaz DOES remove most of the metadata, and replace some with their own.
It removes almost all metadata regarding camera info, lens, location, exposure, speed, etc copyrights UUID and much more.
I don’t understand why a software geared towards photographers would do that.

Here is what I have now vs what I should have

This still seems to be an issue.

I’m on Topaz Photo AI version 2.4.2

Using Olympus E-300 and E-510 DSLRs. Running RAW files (ORF) from them for RAW Denoise processing. Some Exif Data is not preserved when saving the file from Photo AI to a new file.
Specifically did a RAW Denoise process, saved as DNG or JPEG and I noticed that the lens exif data was not passed across to the newly saved file, same with the focal length in 35mm equivalent, serial number.

This was noticed in stand alone mode and not as a plugin through Lightroom.
