Why do you say shutter speed and focal length?

1, I have answered this strange shutter speed in your last question.

2. Regarding the eccentric focal length of 340/ 10mm, you can check the properties of the photo, which is clearly marked as 34mm, but the shutter speed cannot be checked. There are two possibilities, one is that there is an error in exporting the software, and the other is that it is confusing.

Supplementary answer:

Your verification also shows that there is something wrong with the labeling of the photos. As for why, there is no need to get to the bottom of it unless you find the photographer and ask him yourself. EXIF is only used as a reference, so you'd better focus on the photography itself.
