The only thing that can cause this illusion is if you are reading these PDFs with calibre's internal viewer. If you go to preferences - behavior and uncheck PDF in the Use internal viewer list then these PDFs will open in whatever viewer you use to view PDFs.
If you use the internal viewer to view the PDF files the first thing calibre's viewer does is convert the PDF to a temp html/epub file for viewing. This can cause the PDF to look like junk. The actual PDF file is not touched.
One other thought comes to mind if in Preferences - Adding books - Automerge books checked with ignore duplicate formats selected. Then you add a grunch of books, the first pdf added called xyz is added and every subsequent pdf that matches this will be ignored. So if the first xyz pdf was crap and the second xyz pdf was great you get the crap book in your library.

Saying that calibre trashed your PDF files on import to calibre doesn't make it so. Calibre has over a million users and you are the first person to make this claim.

Not necessary but having a backup is always a smart move.

There are countless problems using PDFs as source files in calibre, that is why
this sticky post exists. I don't think you're making anything up, but you have not read any thread or post that outlines PDF problems similar to what you are experiencing.

This is a good idea. Open up a ticket to report this bug in calibre's tracker and attach these two files to the ticket. Find out
how to create a ticket here.

It does both.

Not only would you not want a program to do that as hard as I try I can't get calibre to do what you describe.

The only books that calibre alters on import are html to adjust for the various encoding. Source books imported as html should be retained until the copy in calibre is reviewed. On import calibre doesn't alter any other books at all.

Maybe, look into
this product.
